OMGosh! That is funny. The first pic looks like it has a spinal column at the back of the desk on underneath side going to floor. What is that?
I perused the paper today and found an auction for this Saturday and one a week after. Both have old treadles available.
May have to go just to see what they go for around here at an auction.
If anyone lives near Charlestown/Martinburg, VA area, there is a huge auction there with a very nicely kept treadle in cabinet. They did not show the actual machine, but the cabinet is a four drawer and looks great. I found it on some auction site I can't remember now. Sorry.
