The OLYMPIA page has been updated and corrected. OMEF 1980 expanded the serial number range of existing models (SM models gained *13* years of new serial number data and is now complete from 1950 to 1979!)
In addition to expanded and corrected date ranges for SM1,2,3,4,5,7,8,9, SF & Traveller, SG Models and most of the SGE models, we now have coverage up to 1979 for: Olympiette, Report, SGE 77,65,60,45 and SKM, models that we had nothing at all on before.
There’s some confusion between Schramm 62 and OMEF 80 on the SM2 model, similar to the confusion over Olivetti Lettera 22’s. In both cases the data from both sources is presented, with a note stating which I think is more credible.
If you’ve dated your Olympia before, please date it again using the new data. I had to correct a few typos made in the original numbers from Schumann’s data. If you weren’t able to find your date before, try it now!
UPDATE: I took a look at Source #25 and found a wealth of pre-sovietization serials for Olympia which corrects and expands Plana, Progress, Simplex, Filia and Standard Model 7 and 8, and *also* presents all new pre-war data on Standard Model 3 and 4. This has all been added. (Thanks, Georg Sommeregger!) (:
