Vintage National cash register keytops arts and crafts

Description

40 randomly selected (there may be duplicates) new old stock plastic keytops, as used on several models of the 1940s -1960s. Assorted colors.
( If you'd like all that I have, about 1000 + or -, with a very small number of them being used, let me know and I'll create an ad. 0 shipped, would do the trick)
ps: I added a couple of closer up photos of a few randomly selected, to better show the details of the fronts and backs.
(These were designed to be applied to heated  metal stems of the cash register.)
