welcome to the forum, not sure why we'd email direct, that defeats the purpose of the forum
I can not tell if it is matched or mismatched, but in this condition, I would imagine it is worth around $400-500 - maybe an extra 100 or so for the holster (would need more pictures of it)
condition is a bit rough, but this is what I see, a WW1 (1916 DWM) luger that received the 1920 property marking, went into police service (see front strap); the magazine is probably repairable, but is pretty toast to most people unless they have parts.
Is there a loading tool in the small pouch? if yes, than another $40-$60
