I don't know when the "red caps" came in, but a Hammond service bulletin 
dated January 8th, 1965 tells us that they began the R/C networks on A-100s 
with serial number 40029, but it also says the first one was 24821. Perhaps 
a misprint that meat to say "A-101"?  First A-102, 41525, A-105, 26416, 
A-122, 27947, A-143, 40993.

As has been discussed before, Hammond used parts until they were all gone 
before switching to newer parts, so it doesn't surprise me that a few of 
them might have a mixed set of caps. This must be more than a little 
upsetting to the anal types.  ;-)
