Okay, even if we can't see the numbers under the solder, 6381 doesn't work. That would make it the 81'st week of 1963 and that doesn't compute. So, in my opinion these pots are not the standard pots used by Mosrite. They have most likely been replaced. The wiring doesn't look original either. The solder job looks to not be factory.
I looked in my collection of serial numbers and found another "2nd". That is interesting to me because 1972 is when Mosrite started back up after the bankruptcy. Yours is now the second 2nd to pop up. I don't know if these were truly 2nd's or if they were give away guitars. Semie Moseley donated a lot of guitars to churches, etc.
The other guitar in my database is also a 1972.
Here is what is stamped on the fretboard.

It is also a CE-III but in Sunburst.
