I realize this is the S&W forum. I also realize you are all very very good with info on guns, S&W or not.
I have the opportunity to obtain an HK4 with a complete barrel set as part of a trade. Can anyone fill me in on these? From what I've found so far this is a very early model as it doesn't have the ULM proof marks on the barrels. It also appears to be unfired and in excellent condition, the box is in terrible shape but it does have the test targets that match to each barrel and both extractors.
Any info on the gun and it's value would be a big help, Thanks!
