Hi Power Dates of Manufacture

Below is the key to FN dates of manufacture via the serial numbers.

Per "Browning Dates of Manufacture", 1988, Brownsboro
TX, Art and Reference House:

Z = 1

Y = 2

X = 3

W = 4

V = 5

T = 6

R = 7

P = 8

N = 9

M = 0

Earlier codes; 1954 to 1964 = 70000 to circa 115823, '64 to '69: T136568 to circa T261000, followed be the introduction of the 2-digit year code and "C".

For example, a Hi Power made in 1973 would have a serial number starting "73C…" and so forth.
