$1999 was just starting price, there is a hidden reserve. Real nice 1900 on gunbroker.com, IMO, is not this one. At least, this one's grip panel has a chip.. The one that I like most is this TE from luger666:

The finish is obviously original. From viewer's perspective, he should clean up the bore a little bit. That bore picture (picture #9) may worry some viewers. But consider this was a test pistol, that's normal even if the bore is not excellent.
Hope I had $$.
