Numbers written on barrel and frame?

[Jaybr]

Hey Folks,

Been a while since I visited and I have a question. I picked up a new K40 Elite today that I ordered online from a shop in CA (never thought I’d buy a gun from CA ). I noticed when I took it apart that is has a handwritten 13 on the underside of the barrel, and a 14 on the inside of the frame, both in red sharpie.

Anyone seen this before and any idea why it’s there?

I bought it new, so I’m hoping this doesn’t indicate a gun that was sent back to factory for repair.

I've never seen it, but it could be the same thing the Big 3 used to do back in the day to show who inspected the part(s) passed muster before assembly.
