65 Dist date codes...revisited

Need a little help understanding Oct-Dec '64 distributor date codes.

My review of Tony Gregory's 'The High Performance Mustang' and Bob Mannel's 'Mustang & Ford Small Block V-8' has only further confused me.

Bob's book, p5-40(d), shows a C5OF-12127-E FOMOCO bearing '4LE' date code (Nov'64 5th wk).

A friend has recently shown me two of his distributors both C5OF-12127-E FOMOCOs. The first bears date code '4MB'(Dec'64 2d wk).

The third distributor has me confused,it clearly bears date code '5KB'. Any ideas? An Oct '64 should bear date code '4Kx' and these reference manuals do not list 'K' as a date code month for calendar year 1965. It doesn't look peened or re-stamped.

Thanks

It appears you may be confusing scheduled build date month codes with date codes on individual parts. Keep in mind there were many different formats depending on the part. 5KB on a C5OF distributor would simply mean a 2nd week of October 1965 dated part.
