I realize there's a ton of info online regarding these stencil horns (a head- spinning amount really) but I simply want an idea about the age of this tenor I just picked up. Very Conn-ish in many ways so I'm assuming it's a Pan American stencil. But somewhere I read that this model would be a stencil of a New Wonder, 20's or 30's vintage. This one has same- side bell keys, set screws on posts, etc. And has a serial #62414 which, according to PanAm lists plus it to 1946-7. More 16M/10M than NW. I'll try to add pics and appreciate any info. Thanks all.
