What year was my browning t bolt 22 long rifle made?

[DB53]

I can’t seem to figure out my manufacture date. It is (52100 X7C) if anyone is able to help me out. Thanks in advance

I’m wondering if maybe the 0 wasn’t punched fully, X70 instead of X7C

Well, you might take a picture of the digits in question and post .
Well, maybe take a close up high resolution and do some photoshop work to determine if the letter should have been a number.
