byf 41 and holster

[i8tokyo]

Hello all. I have been a lurker here for some time, amazed at the passion you folks have for the Luger and it's variants. Now comes the time to ask for some insight from you.
Last year my father pasted away, among his belongings was a war trophy byf 41 Luger. The numbers are all matching, the finish is original with no pitting and only slight bluing lost from holster wear. It has one matching magazine, a takedown tool marked 655 below an eagle proof-mark. The holster is in good shape and marked OLV 40, an eagle perched on a swastika with WaA279 directly below. I took it into a local gun shop recently to have them place a value on it for insurance. They told me that $650 is the normal price for one in this condition, and added that the holster wouldn't be the one that the gun would have issued with. I thought this a bit low, and would like to ask you folks your opinions. I'm not really interested in the holster, as I understand they can be hard to keep in good condition. I don't ever plan on selling the Luger, but would like an idea of it's value.
As to the background on the luger: I know my father had several of these as war trophies from his time in Europe, and believe this one is the one he received when a German soldier surrendered to him. I have found no papers as to document him bringing them back, but I know they have went un-molested since he returned from the war. Included is a few pictures to help with your advise. Thanks in advance for any insight you may have..

Best,
Don
