Are these consecutive serial numbers the point of demarcation for the A risers ? Last of the first model, Raised Heel Ridge A-2038 (RH); & first of the last model, Low Cut Shelf A-2039 (LH) ?
Or do Raised Heel Ridge risers exist with serial numbers higher than A-2038 ? Or do Low Cut Shelf risers exist with serial numbers lower than A-2039 ???
Needless to say, I am looking for risers A-2037 and A-2040 (it was shown in the 1971 Bear Catalog), as well as for any limbs with serial numbers 2037, 2038 or 2039.
