New to here and have an interesting gun in my collection. I'm a avid target shooter and love to shoot and collect firearms. This rifle however sits way back on the safe due to its beauty and serial number... It's a riihimaki 222 mannlicher I inherited from my father. He's not around to tell me about it but I know he had it prior to the 90s and wasn't into buying, let alone keeping an "illegal" firearm. I do however think he might have traveled out of the USA with this rifle possibly to hunt. So the serial number has been literally ground down horribly by either the worst gunsmith or my idea a customs and border officer possibly? It has been restamped with the serial number but to me looks more like a date then a serial number. My father would have had this rifle repaired by a professional if there was something wrong with it, which leads me to think there is a interesting history to it. I've attached a few pics. The serial number picture has the final number edited out but is a 5 digit serial. Any thoughs questions or answers would be appreciated. Should I get the Sako signature and factory dates? Why would anyone ruin the receiver so bad and the restamped the numbers like a date? The gun shoots amazing and is 95%+ in my opinion.
