1 patmcmac 4 months ago Big thanks to the sharpies in this discussion group, I have finally clarified the model of my old Gretsch-made archtop, Model 25. It is branded "Tosi", which was a music store on Hanover Street in Boston's North End.Also, thanks to this group, it seems the serial number, which is 170, is very early, possibly 1932. Holy Cow!Am I right thinking that this one was made BEFORE Gretsch started putting their own name on instruments? My pix aren't great, but I can say that the first digit of the serial number looks like a 1, and not at all like the second, which is definitely a 7.Can y'all confirm or deny my theory, please? I'd love to know.Thanks PMac Guitar Slacker PS- I am new to this forum: am I limited to one photo per post?
