More or less the same horn...

For Pan-American saxes I use the Conn Loyalist Pan-Am Brass list http://cderksen.home.xs4all.nl/ConnSerialsPanAmBrass.html and sometimes a bit of extrapolation based on features.Serial numbers on stenciled instruments rarely correspond to those of their manufacturer. This is no exception...it can't be dated using a Conn serial number list/chart. With stencil's, most of the time the most accurate means of dating are educated guesses based on the design features the sax has.
With stencils, they (more often than not) were based on older models that were no longer being produced as a main line instrument. So while it wouldn't have directly competed with Conn in terms of features at the time it was new, it is still a great quality Conn-made sax (just a bit watered down).
