Help with small Luger collection

[DougO]

I recently purchased a gun collection from the family of a collector that passed away. Included were a few Lugers. I don't think that any are that fantastic, but help in identifying them correctly and any help on price ranges for resale would be appreciated.
Thanks, Doug

First up is probably the worst of them, a mismatched 1917 DWM:

Luger #2 is a DWM No Date. Is this a commercial model? If so, any idea when it was produced?

#6 is a DWM No Date, but it does not have the lug on the rear of the handle for the stock. It also has some odd stampings on the front side of the grip. Any information on this gun would be appreciated.
