It seems that I have agreed to purchase a Pak 38 that is located only ten miles away from me in Texas. It will need to be restored and has a hole in the barrel - part of the demilitarization process to get it imported. I plan on shooting with it one day. May I ask if any of our members have any technical manuals on this gun or perhaps the optical sight? It is my understanding the current owner has already amassed most of the parts needed to restore it. Thank you for your help.
