WOW... Today I went to a went to the wrong thrift shop and found the Brunswick Treadle with the instructions and probably about 15 griest feet. The price was insanely low "$90.00" and I thought ugh!! This machine will probably need work. But, I bought it anyway. Then the guy at that shop directed me to the shop I was orginally looking for. I go in and find the Singer model 15 again the price was unbelievably low. "$9.00" And a box of Singer feet for $5.00.
I got home and couldn't wait to play with them! YES! They both work, so smooth they almost purr!
