An intriguing question that I wish I had an answer to. Please do follow-up if you learn anything. I still remember back when I was young(er), self-employed, and struggling. I was offered 2 pistol in the same week; 1 was a Danish contract P-210 for about $700, and the other was a Behlert 1911 Series 70 with a lot of bells and whistles for $550.

It was one of those times when I had the money but couldn't afford the items...both of those guns still haunt me.

Good luck on your search for info.
