Product Overview

The Conn Connstellation 38B is one of my favorite vintage trumpets! I've added a few new horns to my collection recently and my one horn in, one horn out policy is the only way to keep my collection manageable. Plus, a horn this good should be out there getting played! It does have a few little blemishes but the valves feel great. There are a couple dings on the bell bend and a small dent in the bell at the second valve. There are a few spots of redrot developing in the tuning slide, and one small dent, but no leaks. There's a small dent on the second valve slide crook. The first valve trigger is missing the stop nut. There's some lacquer wear around the horn, make sure to check out the photos. Valve compression is quite good, and all the valves and slides move freely.

The Connstellation horns are so much fun to play, and the wider wrap gives a lot of character to the look and the sound of the horn. You also get the great efficiency of the .438" bore!

Conn Loyalist says:

There has been some confusion over the fact that Connstellations from different years look a bit different. So I have decided to "split" the 38B Connstellation into a page for "Early Model" and "Late Model" as I have done with some of the other models. The Connstellation pictured here is the "Early Model". The difference with the late model is mainly in the design of the leadpipe and the engraving on the leadpipe. As for the engraving on the leadpipe, the "Early Model" 38B Connstellations have "Connstellation "B" engraved on the leadpipe in addition to the "Connstellation" engraving on the bell. The late models only have "B" stamped on the leadpipe.

The Connstellation 38B is nickel plated with brass trim and has a large 5 1/8" bell. It has a #1 bore (0.438"), and was produced from 1956 to at least 1979.

There are several variants of Connstellation 38B. The 1956 and 1957 versions (pictured here) used a style of valve cap that was specific to those years. It is a felt-less top valve cap. From 1958 Conn switched all trumpets and cornets to a style of valve cap with the felt on the top valve caps itself. These valve caps are either nickel-silver plated or lacquered brass. I suspect that from late 1959 (serial numbers 800,000 and above?) the rule was to equip nickel plated, nickel silver and silver plated instruments with lacquered brass valve caps, and lacquered brass and coprion instruments with the nickel-silver valve caps.

The issue of whether Connstellations have a Coprion bell has been discussed here in the past and different theories exist. In August/September 2009 I received information and then, by chance, strong evidence that has caused me to change my views on this again.

A former Conn employee said, and this appears to be confirmed by the 1960's Conn Product Manual and other reports, that Electro-D is a similar process to Coprion using non-copper metals. The former Conn employee said that an Electro-D bell was a brass bell, electrolytically plated with copper, and then electrolytically plated with nickel. These descriptions seem to match with each other and the evidence. This causes the Connstellation serial numbers to come in as follows (my educated guess):

Serials (5xx,xxx - ) 6xx,xxx: "Electro-D" bell (see above), Brass leadpipe (multi-piece). "Early Model" Connstellation.
Serials 7xx,xxx - Rxx,xxx: "Electro-D" bell (see above), Coprion leadpipe (seamless). "Late Model" Connstellation.
Serials GA3xx,xxx and higher: Brass bell, brass leadpipe (who knows). "Late Model" Connstellation.

Don't confuse the 38B with the Connstellation 28A which is actually a long cornet. It can be very difficult to tell the difference between the two. Here are the two ways I know of. The first is to find out if it takes a trumpet or cornet mouthpiece. Connstellations built during the period that the 28A Connstellation long cornet was also in production will have a letter "A" or "B" stamped on the mouthpiece receiver. The "A" indicates a cornet leadpipe (28A long cornet), the "B" indicates a trumpet leadpipe (38B). The other way is subtle distinction, but should be apparent in most pictures if you know what to look for (and it is also the reason the picture on this page was changed; the previous picture was a 28A I now realize). If you look along the leadpipe you will see the diameter of the leadpipe increase immediately after the finger hook. This extends to the main tuning slide. It is where the main tuning slide inserts into the leadpipe. On a long cornet the length of this tubing with increased diameter is only half the length, and it starts halfway between the finger hook and the main tuning slide. See picture. Also see the 28A for a picture of this (that is the picture previously on this page). This might also be a way to distinguish a "real" 38B from a 28A with a replacement leadpipe/mouthpiece receiver. The internal bore and taper (conical-ness) is quite different between the 28A and 38B, but this isn't obvious from the outside.

Interestingly, the 1955 Conn catalog lists the 28A, but doesn't yet have the 38B Connstellation. In stead it still lists the previous model, 28B Connstellation. Does this suggest that the 38B is a trumpet version of the 28A long cornet?

The 38B Connstellation is the succesor to the 28B Connstellation, which also featured the first slide trigger. The 36B lightweight Connstellation came out in late 1959. It has a smaller bell and the 38B has sturdier bracing than the 36B. This can be seen by comparing the main tuning slide brace of the 38B pictured here with the 36B picture on its own page. Early models 36B, through at least 1962 don't have a trigger on the first slide. Later models 36B (at least 1966 and later) do have the trigger on first. Otherwise the 36B and the 38B are the same including the nickel plating. This makes it somewhat difficult to tell a later model 36B and a 38B apart. The quickest way to tell the difference is to compare the bracing. The other option is to measure the size of the bell.

Apparently Conn (UMI) tried to produce 38B's again at one point but couldn't get it quite right. Going back to the original specifications and tooling wasn't an option because those had been destroyed at one point.

What Conn said in 1957:
The "last word" in trumpets... this brand new model is a fitting companion to the great 28A Connstellation cornet. Many artists use both- the cornet for small combo use and the trumpet for larger groups and solo work. Features amazing ELECTRO-D bell, top spring clickless crysteel valves, non-corroding "Micro-Finish" mouthpipe and scientific CALI-BORE. Nylon piston guide reduces valve noise at the same time adding longer life to the part as compared to former metal guide. Trigger mechanism on first valve gives great flexibility in both high and low ranges. Length 21½", weight 2 lbs. 12 oz., bell diameter 5 1/8". Outfit includes new, modern Connstellation case.
Highly polished nickel finish, with brass trim, protected by longer lasting, acid resistant LUSTRE-CONN finish.
