So, the two F122s arrived today. One from April of '85, the other from November. It took them 12 days to get here, but that's forgivable given that they were being shipped across an international border. Packaging was great - both keyboards wrapped approximately 3x in the larger size bubble wrap, with a few extra sheets of bubble wrap inside a pretty heavy-duty carton. Zero damage in shipping, although I did have to re-seat one spacebar (the stabilizer had slipped out of its supports).
The boards are near immaculate, they appear almost unused. I'd say they must have been NOS, except that each of them has a small blemish - the one from April has a teensy crack in the case under the spacebar; it has been fairly cleanly glued up and nearly escaped my attention (This board is also assembled with some sort of security torx bolts, with a post in the middle? Never seen that from the factory). The November board has some small abrasions to the plastic that expose the substrate underneath, like Fohat describes can happen with these Fs.

Top keyboard, the M122. Yes, it's a button-leg M122 from 1990! Huh? *shrugs*
Minor damage to the April board (sorry for the poor photo). It's a hairline crack in the case below the spacebar, and was glued up and repaired at some point in the past:
Minor plastic abrasion on the November board:
Pretty!
In short, WELL worth the price; some of the best ebay boards I have ever gotten.
