Thank you for a great trade. I really think I'm going to like that H&K. That knife is cool too.
I hope you and your father enjoy that Smith & Wesson Model 48-4. It is a piece of history and somewhat rare. It's hard to find one with a 4" barrel in that condition with the box, papers and tools. Make sure to try those grips out. If your not going to use them, you could probably sell them for at least $100. I think I paid $120 for them.
