Sorry if I'm posting this in the wrong place but I have a k-22 and was hoping to get it dated. But I'm trying not to take off the grips. It has two other numbers stamped into it that says "k 17507" and another that reads " E
11093.
8 "
Can the shipping date or manufacture date be found using these two numbers or do I have to dismantle the grips to find the date out?
