SN is 1A-1918923-12. it looks very similar to the 1941 gallery, but presumably they didn't change much during the war. I'm surprised there are SN's for the war years at all, frankly, but I guess donations didn't cover every need.
I just need to get a new ribbon in here and use it some more.
In other news, I was outbid on an Olivetti Lettera 36 electric portable. I only tried for it because of the floating keyboard as seen on the Praxis 48.
