     FWIW, my SCR-211  BC-211 AN had a contract date of 1945 
and an MFP stamp for March, 1945, the RA-133 power supply 
has a contract date of 1948 and an MFP stamp for December, 
1948. Since both are very late production they may be 
different than earlier ones. Its still not certain they were 
MFP treated at the time of manufacture but, if not, it must 
have been soon after.  Other equipment I have or have seen 
has MFP dates sometimes much later than the estimated 
manufacturing date.
