These are in rare 64ths size increments and not the usual 16ths. I’ve searched around the internet and have not found other examples of these collets in 64ths -finding even one example is pretty difficult let alone finding 29 of them. I don’t know how many were in a complete set, but this has got to be pretty close to being complete. Not only that, these are also in excellent condition for the most part. They were stored in oiled wax paper all these years so they preserved really well. Size 13/64 is the most stained (see image #22), but that is the worst one, the rest only have minor stains or non at all. 11/64, 13/64, 15/64, 17/64, 19/64, 21/64, 23/64, 25/64, 27/64, 29/64, 31/64, 1/2, 33/64, 35/64, 37/64, 39/64, 43/64, 45/64, 47/64, 49/64, 51/64, 53/64, 55/64, 57/64, 61/64, 63/64, 1-1/64, 1-5/64, 1-7/64.
