Your machine is not only pretty, but also very interesting!
So, after asking on the typewriter Discord, people there confirmed my suspicions, there’s something off with this number: it lacks a prefix and is black on white while normally they are white on black. Conclusion: it’s probably reinscribed, so there’s no way to know if it’s the original one or not.
However, the features are coherent for a machine with that serial, so it’s probable that it’s the original one, but reinscribed after a service, for example. So it looks like you have a machine constructed within the first year of production. It turns 100 this year, or in 2026, that’s cool :-).
But there’s also an other possibility: there’s stories that typewriter enthusiasts tell each others around campfires that some Underwood could have been assembled in Europe. Is the country of fabrication mentioned anywhere on the machine? Probably in the back, under the patents?
I never watched an X-men, nor the old Dune, so for me Patrick Stewart is Jean-Luc Picard.
