52D and E comment
Just a short comment for Johnny O. You ask if anyone has anyone ordered a 52D and received an E in the 1960s? I can't help there but I have in my file a xerox of a Winchester factory invoice for eight Winchester 52Ds, each listed individually by sn and all are numbered as 52Es but are itemized as Ds. This invoice is from late in the production cycle, 1978 or '79, I'd have to check which. To date, that's the ONLY piece of definitive evidence that I have seen that bears on this question.
I haven't checked my file lately but I've got more than 300 serial numbers for 52Ds and over 200 for the E. Each new number is important in that I think I can begin to see manufacturing trends - that is there seem to be blocks where a particular model (e.g. International Match or Intl Prone) was made. Many of the 52D CMP rifles seem to also fall in blocks, probably related to particular contracts.
Not to pile on Herb Houze, who wrote a magnificent book (I've almost worn out my original copy) but the sn data show that he is incorrect in his statement that large sn blocks werre left unmanufactured. The numbers I have are uniformly spread through the entire range for both models. If there are gaps, they are limited to a couple hundred rifles AT MOST. As new numbers come in, these gaps get smaller.
If anyone wants to contribute serial numbers to this project, I guarantee absolute confidentiality in terms of ownership info and I would use your entire number in print only if it were historically significant (i.e. the lowest or highest number of a model, etc.) The complete number is much more use than a partial number because of their role in filling gaps (two x-ed out digits leave an ambiguity of almost 100 numbers). Details as to stock type, barrel weight, bolt configuration, muzzle counterbore, trigger, purchase date, etc. are welcome.
I guarantee an individual response to your e-mail and absolute security for your identity.
