I found the Televideo through one of the "great finds" forums, either here or on DT, I cannot recall which. I'll post some photos once I get the keyboard and disassemble it. It was a little more than I was hoping to pay. The proceeds went to charity, at least.
Not MX compatible you say? Ah well. I'll break out the calipers once it arrives to see what is going on there. Maybe they can fit with a shim if they are oversized.
Back in the good old days Model Ms were $5 at thift stores and $20 on eBay. How times have changed.
nubbinator I'll PM you if I decide to pass it on.

Since my last post, I received some doubleshot Esc keys from Signature Plastics, a DCS row 1 and an SA row 3. Even SA row 3 is much less tall than OEM profile row 5. Compared to Vortex PBT doubleshots the keys (particularly the DCS) feel like a feather - super light. Makes me think that a set of SA row 3 or row 2 would be perfect for a keyboard like a Model M with a curved back plate.
