Pan American Brass Serial Numbers (rev.1)

This page contains a list of Pan American serial numbers for brass instruments. That includes cornets, trumpets, horns, trombones, euphoniums and basses. It appears that Pan American woodwinds (saxophones, clarinets, flutes) use a different serial number list.

NOTE: I have come to believe that Conn bugles go by the same serial numbers as Pan American brass. Therefore, this list should also be valid for Conn bugles.

How this list came about
This revised serial number list is mostly a result of hard work by Kevin McKnight. It is a work in progress, so future updates are possible. It is based on serial numbers collected from November 2013 through February 2014, with a sample size of 714. Of these 714 instruments, 64% are cornets and trumpets. Eight models of cornet and trumpet were chosen to control the data points, representing 72% of cornets and 67% of trumpets.

A few remarks
First, there is some confusion about serial numbers starting with a "P" and either followed or not followed by a dash ("-"). The easiest way to determine whether the "P" serial is a 1971 or a 1920's instrument is perhaps this: If there is a model name engraved on the leadpipe, most probably "Director", then it is a 1971 model. If it has "Pan American" engraved somewhere on the instrument, than it is most certainly NOT a 1971 instrument.

Further about "P" serials: these run concurrent with this list. So if you have an instrument with serial number P23456, then look under 23456, without the P.

The serial numbers in a particular year start with the indicated serial number. So for example, serial numbers for the year 1921 run from 19167 to 25333 (start year 1922 minus 1).
