Vintage Antique C.G. Conn Slide Trumpet - 1920 | eBay

There's been a few of them lately. Here's mine . . .



For years notta, but then a bunch of them. I'd still think pretty rare as they were likely never a real big seller. More of a novelty item used in vaudeville mostly.

i've seen about 4 of them on eBay the last few months. I think there may be one or two right now maybe.
