The pot is dated 137 7346, so the 46th week of 1973. This seems to be a very common pot date for early MXR pedals. They must have bought a ton of them.
The chips are dated the 39th week of 1973.
I replaced the old deteriorated foam, but you can see lots of particles left over on the board. The only thing changed is the battery connector, I think. Oh yeah, and the screws look too new, so are probably replacements...
