Just acquired a Lettera 22, Ivrea, round key tops, non-embossed "Olivetti" logo, clip-on flap case, serial # 440912. Blue body but brown paper table, suggesting a repaint right? But a really good one. can't see any original brown on the rest of it...maybe a shop just swapped out the cowling at some point.
Anyway, how to date this? According to the serial number database, I think round key tops would put it in the first year of production ("up to 904000"). Or 1954 according to the "alternate and possible erroneous from OMEF" data listed there ("up to 626232"). But wouldn't a mid-fifties machine have square key tops? The "Year by Serial Number" photos page seems to have round tops 54-56 that are close to this number...
I guess I am wondering when they left the round for the square key tops, like the 32 has. If that is the deciding factor.
Pics when I can post them. It is a bit mildewy but still functional, original drawband even, just needs a clean up -- pretty excited.
Appreciate your help!
Thanks!
