Congratulation! great news-I had a feeling when you first posted,you would get some gear back,its great news
Did the police say anything to you like 'additional information' on how they got it back etc? usually they do not. Whoever stole it had no idea what its was-I bet they tried to sell it at local pub,and got no offers.
This is the second time this year I have heard police return stolen good to owner-a bloke down the road had his 22/250 stolen seven years ago-kept the bolt in his glove box all that time,and now he has the rifle back.
