Help valuing a Martz Luger

[Bluznvice]

Since this is my first post, I'll apologize up front for any inevitable mistakes I make in this post.

I'd appreciate any help you all could provide in helping me determine the value of this luger. Somewhat of a long story here, so bear with me please...

My dad became acquainted with John Martz in the early '70's. They were both in the military and worked in the same area. Dad was an avid collector and sometimes shooter of many types of guns, but John got him interested in lugers. As a side note, I was very sad to hear that John just passed away. I was hoping to get in touch with him about this one. Anyway, in the mid-'70's dad ended up buying at least 3 lugers from John that I know of. One he sold, another was stolen, and I have the last one.

From the notes and receipt I have for this gun, it appears that dad wanted John to build him a nice shooter. He ordered it in December '76 and John finished it in February '77. John described it as a "Martz Custom Shooter Luger". The receipt indicates:

- Basic pistol, 41-byf-#411
- Custom Luger 6" - 9mm barrel
- New grips
- Satin white refinishing
- Trigger work (easy pull, no free play)
- Custom wide front sight
- Custom wide square rear sight notch
- Reform & rechecker grips
- 1 box new Winchester full metal case 9mm (John specified to use this ammunition)

Apparently, dad wasn't satisfied with the magazine because a couple months later there's a receipt to "find mag to match conformation of handle - polish button - re-test fire".

So, there it is. I'm not sure if dad ever fired it. It looks mint, and appears to have the old grease still in the barrel. That wouldn't surprise me. Sometimes he never got around to shooting everything he collected. I'm kind of afraid to look around for the box of Win ammo since I probably shot it up a long time ago, but I suppose I should.

The reason I'd like to know the value is because I'm a shooter and can't stand having safe queens. This gun does have some sentimental value to me, but not enough to not shoot it. However, if somehow it has more value in it's present condition to a collector, well...you know. Let's see if I can get the pictures attached.
