Wow! This model in QWERTY must be super rare, and Fleshy looks immaculate. Congratulations.I briefly had an Olympia 8, and I have an Optima M10. The M10 resembles the SG1. The Olympia 8 seemed like a pretty different beast to me, with a carriage that tilts when you shift, and a very different (not very nice) feel to the typing.
I'll definitely have to check that out when the M10 arrives! The one I bought it from the first year of production, which was three years before the SG1 was introduced. Would be really neat to find it just an earlier version of the SG1. Yours looks fantastic.
