Not quite a clone
Since Miriam was kind enough to post pics of a 15 I figured I'd add to the fun with another Singer. Not Japanese and not a 15 clone underneath, though it sure looks like it from the top. Here's our 115. From above just another 15 with Tiffany decals. From below something quite different. No idea yet if it works as it's further down the line for me to work on. Everything moves, though, so I have some hope.
