Wow, thank you!
I’ve been searching forever, but the only thing I’ve had to go with was the worn “W” logo on the horn. Even if it was cleaned up, it doesn’t have the business name around the outside like yours does. The tag was the first thing that drew my attention in a Google search. Mine is the same shape, but where yours is marked 1093, mine says 1944. Until now, I’d assumed it was a year of manufacture; now I assume it’s a serial number of some description. This one does have a fiberglass tree, but the stirrups are entirely different: they look like a hardwood with a steel wrap rather than the leather that you have there. I’ll have to take a look in the daylight to see what more similarities and differences there might be here, but I’m so glad to have found this post!
Thanks again!
