Hi,
Thanks to everyone for their kind birthday wishes.
As to the NCR's - all from the brass era - so pre 1915. Also from the small candy store types (highest sale you can ring-up at $ .59), to the really big ones including one that is a free standing floor model. That one is 6 cash register in one, and has a electric motor from 1907 that still works. Oldest? That is 1895 - but rarity trumps age. I have a wood one with an in-laid design and side by side cash drawers (from around 1901), that is the star of the collection. Chaa -Ching! LOL
