My new to me Singer Red eye that my brother bought me in INdiana has the back clamping feet. My first one is side clamping. The new one is in a treadle cabinet but needs a new belt. Plus the entire bobbin case is rusted. I got it to spin and the needle move but the bobbin case may be missing a screw or something. I did use elastic for a fake belt and did a little "treadling" with no thread. The elastic keeps popping off...lol. But, it was a Blast!! I think I will really enjoy treadling!! May have to take my motorized 66 and switch it to the cabinet :)
