This page contains a list of Conn serial numbers for brass instruments. That includes cornets, trumpets, horns, trombones, euphoniums and basses. This list is not correct for Conn saxophones (see Conn Woodwind Serial Numbers) or Conn bugles (see Pan American Brass Serial Numbers).
This list undoubtedly still contains errors. If you own a Conn Guarantee Bond I would appreciate it if you could scan it and e-mail it to me. I am interested in comparing the exact serial number and date.
Despite purchasing all of the assets of the Adolphe Sax Company in 1928, Selmer did not start selling saxophones bearing the Adolphe Sax name until 1931. The last Adolphe Sax saxophone recorded in the Selmer Paris archives was sold in 1944. Its likely that production of Adolphe Sax instruments ceased at the onset of WWII sometime after May of 1940. Any Adolphe Sax instrument sold after this date was most likely already made or assemble from pre-existing parts. For example, the record shows that all of the recorded Adolphe Sax instrument sales between 1940-1941 were from instruments already manufactued between 1931-36. There is a fairly detailed record of these instruments recorded in a log book in the Selmer archives in Paris up to 1936 through serial number ~1364. The record is much less complete after 1936. Instruments manufactured after 1936 range in serial number from ~1350-3600. The log book shows the serial numbers jumping around quite a bit for the Selmer/Adolphe Sax saxophones. Even so, its possible from this record to assemble a basic serial number chart for these instruments. Some instruments were stamped H. Selmer and some were not. All were stamped Adolphe Sax 84 Rue Myrha. By comparing early verses later instruments, it becomes clear that some Adolphe Sax Selmer saxophones were assembled from the old Adolphe Sax tooling and other were put togther using parts and tooling from the Selmer St. Louis Gold Metal model instruments.

The main thing you learn from serial numbers is the age of the instrument of course. Although the dates in these charts are reasonably accurate, there may be some discrepancies for various reasons. Here are a few things to bear in mind:
When advertising an instrument for sale, you will often see the serial number referred to as 36xxxx. It is rumoured that there is a scam, by which somebody who acquires your serial number can then claim the instrument is theirs. This may just be paranoia as I have never heard of this happening, nor can I understand how it could happen.
A serial number can of course be used to identify a stolen instrument. If a seller does hide part of the number you may wonder if they are trying to hide the fact that it is stolen. In most cases the reason is for the one stated above, but it is always worth checking when buying an instrument. Ask the seller privately for the number and do a search for that instrument. If it has been stolen recently, the legal owner may have registered it with an online database of stolen saxophones.
Notes: Conn started referring to horns by model number after Carl Greenleaf bought the company in 1915 (the practice probably started in 1922). There is some dispute as to when the model numbers (i.e. "6m", etc.) started appearing on horns, however. This appears to be as late at the early 1940's, but I believe this practice started around 1935 with the introduction of the Artist ("Naked Lady") horns.
As noted, Conn recycled their model numbers more than once. They also did the same with serial numbers in 1976 -- and some serial numbers on Conn's lesser models (i.e. student horns) in the mid 1960's to 1980's had unique serial numbers that have not yet been charted. Thes horns also tend to bear interesting model numbers (18M, 50M, etc.). Most or all of them were produced in Nogales. Pan American horns, as with most stencils and second-line models, have their own, unique serial number chart.
Finally, I'm asked often about serial number and model charts for Conn stencil horns: there are no official charts for either. Stencil serial numbers starting with a P APPEAR to be +50,000 off on the Conn serial number chart for split bell key horns (i.e. a s/n P2xxx horn. 50,000+2000=52,000. According to a Conn s/n chart, 52,000 was made in 1919) and appears to be at least 200,000 off for LH bell key horns.
Conn stencil model names are NOT consistent. Stencils were not exclusively made by one company, but by either the lowest bidder or whomever had the best relationship with the storefront. So, for example, Lyon & Healy horns were made by Buescher, Martin, Conn and Holton at different times. This is probably part of why there is no stencil serial number chart. 2b1af7f3a8
