Looking at the following Luger

[Geo99]

Make sure it functions - you can c0*k it and pull the trigger.
Remove the right grip (the one opposite the safety lever), not the left.
Blue look original, but look for halos - especially on the barrel numbers or witness strike.
Look for cold blue touch-up.
I don't know if you care, but it looks like the straw may have been redone - really impossible to tell from pictures, but very possible if you have the gun in hand to look at the polishing marks and insides.
Check the bore - description is very ambiguous.

Description is wrong -
"very little straw"? I don't know what Lugers the person who wrote this is used to looking at, but I'd say there is still plenty of straw - it's very nice, at least 70-80%.
Magazine is supposed to be nickel plated - no pics, but it could could be a clean factory original.

I disagree with David's price estimate for a 1936 - this gun is worth at least $1800-1900 retail.

David does make a good point about tax, transfer fee, and bidder's premium.
