Comes with one key that operates the drawer lock. Loathe to glue it back on as I don't know exactly which one to stick it to. The machine operates in old British currency, so it must be pre 1970s.I have not tinkered with the register at all, except to clean it. See photos for more details, and feel free to ask any questions. The item "Vintage NCR Cash Register Till Old Currency" is in sale since Sunday, April 11, 2021.
