Oh... I'm grabbing pushbutton cores whenever I find them. I have 2 in the storage as well as 2 of the typewriters, although they are getting difficult to locate complete. They'll often be missing brackets or springs
nice.. I check FB daily looking for cheap cores (upto 76) for spare pumps/input shafts and stuff.... if i find a really cheap pushbutton i will snag it for the case though just cause
