My first centerfire rifle was a Type 99 Arisaka, and I spent a lot of time tinkering with it. The forend was all busted up so I cut it back and tapered it, basically the only modification I did to it. I spent a lot of time practicing my ham-handed metalworking skills (if you can call them that) polishing the receiver. It was a late-war gun, rough as a cob, and was a bring-back from the Pacific Theater with the crest ground off, so I didn't worry about ruining it. I think I paid $55 for it, complete with a box of shells. I'm pretty sure the shells were worth more than the gun. I still have it.
