Welcome to the club - I have my great-great aunt's Damascus. It is also from 1925. My grandmother had 2 treadles and I took the Damascus because it worked and it had the manual. All I had to do was buy a new belt for it. I haven't found much about them but I did find that she paid $25.00 for it in 1925. Thought that was funny. And thinking that was very expensive for the time.
