Looking for my old Sniper, is there a thread for tracking down guns?

[Oddbawl]

I did a search and looked around, didn't come up with anything.
Is there an existing thread where serial numbers or descriptions of guns were looking for is posted?
I would really like like to track down my Sniper II, Ser# 3144.

We do have such a thread.
