What a haul! The Franklin's in amazing condition and the Kenmores are both phenomenal machines. I have a 1503 that is very similar to the 95. The 1503 is one of my favorite machines. I don't have the 1760 but I have the 1913, a model that is a slightly higher end version of yours. It looks like a super-high shank. Take a good look at the presser feet, measure their height, then go on the prowl for the matching accessories. The 1913 is my favorite Kenmore convertible.
Any one of those machines would have been a great, great find -- but all 3? Do machines come in 3s? What is up with that? Congratulations, those are amazing machines.
