Impluse buy. Worth it? (1938 S/42)

[batex]

New member here. Normally, I do lots and lots of research on the guns I come across and end up getting most at great deals. Sometimes, I've missed good deals by not moving fast enough however. In this case however I did not do any of that. I've always wanted a Luger and on the way home I came across this one and just had to have it. I knew enough that all matching numbers was a good thing and 1938 puts it at the beginning of WWII, but still, my emotions got the best of me. Gun appears very clean for what it is.

After doing some research, I think I really overpaid on this one. Is this gun worth the $1500 I paid? (BTW, the pics are not the best. Took them with my iPhone. Gun looks better in the flesh. )
