OK, well, finally scored one of these nasty bastards...
There have been some on eBay, all coming out of Russia and Eastern Europe. All appear to be ground dug and in varying degrees of corrosion from very little to relic condition. I was going to pull the trigger on one, but then found one listed out of Georgia (as in here in US, not Georgia the country
). He had it on Buy it Now, and was probably $100 more than most of what could be had in Europe.
But this one is in really primo shape, and not being in Europe, it wasn't going to take 4 weeks plus to get here, and have a higher probability of getting lost/confiscated in customs, so I bit the bullet and pulled the trigger on the domestic one.
It arrived today, and is REALLY nice, great shape. It is missing the three main detonator bodies, and the shrapnel load (being an early one it would have the ball bearing load, not the cut wire load), the string cushioner, and no fuze. I have several S.Mi.35 Zunders, so I will throw one of them on for now, but I have a nice three way, complete with the 2 Zug.Z 35 pull igniters to put on it, but it will be a month likely before it gets here.
I will pick up a bunch of 1/4" ball bearings to fill it, the string cushioner is easy, and I will be able to find the detonator bodies on eBay in Europe I would guess. The reality is you can't see any of them when assembled, but I can't help myself, have to try to really complete it...
Here are some overviews...
