Hi Anton, I agree with the others that the pics are not detailed enough to warrant an evaluation. $4000.00 is a lot, and more needs to be known. The stock could be worth $1200/$1500. Then is the rifle worth $2500? If you are going to go by pics alone you need better and more detailed pictures. Also does it have any documented provenance that would command $4000? I hope these considerations help. Go slow on this one.
Best Regards.....Frank
