FW's. What an awesome little machine. I have two the black one, 1936 and the white one from Scotland 1964. The black one we bought at an antique flea market and paid $450 the white one DH found at a yard sale and they thought is was a childs toy. Paid $75 for it. I also have high end machines, but recently I've started doing all my piecing on the FW. Such a true stitch. One quilt I was making called for scant 1/4" s/a so I used one with a guide and the other FW for the 1/4" seams.
