Thanks for the info-you explain things well.
I think I may have a treadle and all I really know about it besides it being a Singer is that it is Heavy!! That'll have to be his name. My husband and I were out walking our dog in the neighborhood and found Heavy sitting near the road waiting for trash pick-up. My husband casually scooped him out of the trash and we continued our walk. We were probably only six blocks from home but it felt like miles! I volunteered to spell hubby and lasted only about a block.
We hoisted Heavy onto the top of our entertainment center and he's been there every since. I'll have to climb up and dust him off. His serial number is AJ434948.
I like the idea of rustic rockers with wide arms to balance our beverages on and a deep wide seat to curl up in.
