Probably IF and RF are intermediate and high frequency, respectively,

I sorta figured what the IF & RF were for, but not the numbers....the FT
had me stumped. FT as final test makes sense and the T18 would translate
to Technician #18. Cool! Now for the number under the Mark 1A (199907).
It's not a serial number--that's on the back of the chassis on a paper
label. Any ideas??
Yea, I know. It probably doesn't matter. I'm sure these stamps will be
gone by the time I finish cleaning, and curiosity has gotten the best of
me.
Thanks Mike!

I would leave the marks there! I think that the "mark 1A" is the
version number. I think there is a 2A etc chassis. I don't know what
the difference is. Maybe small wiring differences.
