This is really interesting. Most of my knowledge is up to 1935. It's my understanding and I may be wrong. The collegiate line started around 1933. End of the revelation era. At the same time this is definitely a left-hand Bell key & 19xxx is a 1925 number. There is no Eb above the serial number. Also no model designation number. I'm not entirely sure when the collegiate line began model identification. I.e. 566 above or below the serial number. The Bell engraving design appears to be early format. The RH key work is definitely not 1920s. The silver key pictured is 20s keywork. Compared to the brass pictured. What's really bothering me is the round escutcheon plates on the key guards. Holton's are always diamond shaped. So....Collegiates go back to then 20's...but indeed 19,XXX puts it at 1925 and that is a same-side bell key horn...so it doesn't seem to me it could be from '25.
But then again, Weidoft models started being produced in 1925, and THOSE were same-side bellkey horns...so...(?)
A bit of a head-scratcher....it'd be interesting if Holton actually used the same bellpiece as the Weidofts on their Collegiates...
@PigSquealer is a Holton fan, maybe he has some explanation...?
i'm guessing this is a 1925 body tube and serial number. It has modern key work of the collegiate line. The bell body is old inventory from the Rudy Era, engraved Collegiate. The wire guards are from 1928 Couturier parts.
Late 1933 to mid 1934.
