My H&K 91A2 has a "IB" code on the receiver.

What year was it made?

Thanks,

Copied from HK PRO:
The date coding system is very simple too.  It gets tricky when you start talking about non-proofed products like firearm magazines, but the general rule is thus:

A B C D E F G H I K
0 1 2 3 4 5 6 7 8 9

IB=81
