Bart Vanderveens approach to when stuff was done
Hi All
Years ago I had the pleasure of corresponding with Bart Vanderveen about when certain changes were made to HUPs. At that time some of the data bases which are now available were not. Bart's approach was to look at the changes in part numbers which often include notation of before or after such and such a serial number. Knowing the basic dates of the serial numbers to production dates gives a fairly tight dating. At that time Bart was trying to collect copies of all the various HUP parts books, I mailed him a June 1945 version.
Also at the CMP Forum in 84 memory says there was a discussion of when stuff happened, and a comment was made that cut dates are not as hard and fast as people might thing because parts in process could be used up after the change over date.
Cheers Phil
