There is a lens of the brand J.C. Penney for which I wish to identify the manufacturer. How can I do it?
It seems that it has been common for redistributors to have coded the manufacturer in the serial number. If this is the case of J.C. Penney, as it was for others, then, in principle, I just need to find a list of the applicable manufacturer codes. Yes J.C. Penney participated in this practice, what are the manufacturer's codes for lenses that were renamed J.C. Penney?
