My thoughts, as well.

Do the colors (frame and ST banding) reveal any clues? Usually they do, at least in the early and mid 1980’s. The chain stays look a bit long, and that was a characteristic of the later 1970s. Rear wheel looks like a 5 or 6-speed, so the rear OLD could be 120, 126 or 128,

Some closer pics with a well-focused side elevation with a lot of pixel detail, and a close-up of the frame tubing identification, would all help. I’ve found it really rare that a number cannot be decoded.

Also show us the number in the actual point to see what the actual number could be. Maybe we just need to unscrew a shift wire guide plate screwed onto the bottom of the BB shell. Or, does the fork steer tube show an SN? Usually the numbers on the steer tube are pretty darn clear.

But I think this frame being small, triple-capable, and a well-specced build, could be in the more-desirable category, not to mention the paint is in decent condition, as far as I can see!
