The Luger (P08: pistol model of 1908) is a winner for sure. Condition looks good at first glance. For anyone to evaluate the gun, they'd need to see the other side, and several other views, to really judge the condition. Then close-ups of the stampings, factory and year marks, serial numbers, whatever's on it. Hopefully the numbers match on each part.
Then you'll need a Luger expert, which I am not, lacking a 12(6.1) endorsement on my licence. Either here in the Pistols forum, or down the page a bit to the MilSurp forum, someone will look at the additional pictures and give a better idea. Think around a thousand bucks, but it's variable.
You've got two magazines, which is good; does one or both of them match the pistol?
The Browning far less. You can see the finish is mostly worn off, but at least it's original and not re-done. It's just a less desireable pistol all around.
Both are 12(6.1) Class Prohibited Firearms, and both are eligible for 12(7) inheritance as 1945 and earlier manufacture, so are better than post-WWII Prohib.s as far as the marketability.
