Bought mine around 35 years ago, scoped, pressed pattern checkering for less than $50. $190 now, wow. Still lethal on rabbits and squirrels. About all that has been done to it is a good solid, take apart cleaning of the internal workings every couple of years. It doesn't shoot as well with the light weight, hyper velocity bullets like it did at one time, ~10,000 rounds will do that. Stock, no frill rounds still cycle without a problem and those little furry rodents don't stand much of a chance. Suggest taking it apart and cleaning the blow back residue out of the workings and a good barrrel cleaning, it does tend to accumulate. Model 60 is a tough, simple and accurate little SOB.
First it rained, then it blew, then it frizz, then it snew --- from an oldtimers gunning boat ~~ He understood what it's about!
