C&R are 50+ year old guns made after 189? I think. A c&r gun can be shipped direct to a c&r license holder, if state laws permit which they usually do.
Walther made 1943 P38. Depending on details probably 1000-1250. Looks like a good one.
Can't remember if the single line is more desirable than the double stack marking.
Nice gun, shame about the left grip damage, but that's quite common. If you ever plan on shooting it you might want to get a spare breech block, extractor and firing pin to use. Don't want to risk breaking the numbered parts.
You'll find that things like the extractor, firing pin, 3 parts of the toggle train, side plate, takedown lever all carry the last 2 digits of the serial number. Military guns have these plainly visible, commercial guns are more discretely marked. Mismatched parts can affect the value quite...
The Luger appears to be a common commercial pistol from between the wars. Is it 9 mm or .30 ? Quite a nice gun, too worn for serious collectors and the left grip damage doesn't help.
Need to check if it's numbers matching.
