C2 Original Door Panels: Numbers and Letters Decoding

[Roger P.]

I was curious about the hand-written numbers and letters that I found on the back of my original door panels during my vent windows restoration project. There is a manufacture date stamp of Feb. 11, 1965 and Feb. 12, 1965 on the panels. My car was assembled on Feb. 26, 1965, so the dates make sense. However, each panel has the number "3" hand written. One panel has "B22" written, while the other panel has what looks like either "J21" or "P21" written. In addition, one panel as the letter "B" written while the other panel has the letter "C" written. What do these letters and numbers mean? Are they date codes and/or production sequence numbers?

Thanks in advance, Roger (50141)
