Thanks any info is appreciatedI don't know anything about them, but the only time I ever saw one for sale was marked something like $8000. I have no idea how rare they are or if $1000 would be more market value.
The best source of information is Mauser Pistolen by Weaver, Speed and Schmidt. There is an entire chapter on that model.
Edited to add: There is one on Gunbroker now for $7950 with no bids. So they are apparently considered to be valuable, how much so is a puzzler. I imagine that collector interest is rather limited as opposed to say an 1878 Colt SAA in similar condition which would have a lot of buyers.
