I'm sure not an expert but it looks like one of those newer machines made to look like the old ones. The decals look too new and not quite right. Someone that is more familiar with them will pop in and comment, I'm sure. It looks like it's in a treadle cabinet but I don't see any belt... or where you would put a belt. Is there a motor?
Something just doesn't seem right on this one, sorry. I hope I'm wrong.
