I've got a bike build that I've been "working" on since March. Early on I dubbed it "Project Quarantine." It has gone about as well as the rest of 2020, but I'm starting to see light at the end of the tunnel and feel like it's close enough that I can start sharing.
The project originally started around a frame that I bought from a guy in Europe in early March. There were, shall we say, logistical problems with that. The seller and I both failed to realize that all hell was about to break loose when we made the financial part of the transaction. I won't go into the details, but long-story-short the sale ultimately fell through and my money was refunded. Not, however, before I had started to accumulate NOS or similar quality parts for the build.
Not pictured here, but also acquired, are a set of new DT Swiss R460 rims, some shiny silver Origin8 hubs, and a nice set of Centaur 10-speed shifters.
Naturally, I had to start looking for a frame to go with these parts. I had a pretty short list of frames that I would find acceptable for this project, and I didn't think it was going to come together before next spring, Then last month I found something on the sales forum here. I'm going to leave a bit of suspense as to what it was. The price was right, but the frame needed some work. I never hesitate to sign my friend [MENTION=381793]gugie[/MENTION] up for work, so that was no problem. I even managed to get him to squeeze it into his queue. His original estimate for an opening was Thanksgiving, but then two Saturday's ago I got a text saying that he had to order materials for the projects at the top of the queue, and if I could bring it over that day he could knock mine out. Woo hoo!
So the frame.... A previous owner -- not the BF member who sold it to me -- decided it would be cool to sand the lugs, fork crown, one of the chain stays and part of the seat stay caps down to bare metal.

And then they decided to grind off the bottom bracket and chain stay cable guides. Whoever this madman was proceeded to remove the chainstay bridge.

Finally, for good measure, they cut a square and two circles in the bottom bracket shell (I'm guessing this was done to mount it for display?). Happily, they left the shifter bosses and the rear derailleur hanger. The work was pretty clean, but naturally the bare metal had started to gather surface rust.

(That's a good clue as to what this frame is.)
[MENTION=175671]shnibop[/MENTION], who sold me the frame, had collected the necessary hardware for the cable guides, and [MENTION=381793]gugie[/MENTION] put them in place.
From photographic evidence, I was able to determine that this particular frame should have had Shimano-branded cable guides, but Mark had a solution for that.
