Three keyboards was available during the years for the HP-41C

1. Tall Keys with shining front panel - 1916 up to 1952
2. Tall Keys with structured font panel - 2001 up to 2052
3. Newer Keys “shallower angle” with structured front panel 2101 up to end of production

If he wants a period correct calculator, he needs another front panel from an early HP-41C.

I have a tall key with a shining front panel and a serial number starting with 2010.
