I purchased my Model 41 new in 1980, it's ser # A5825XX, and it has fired many thousands of 22 HV rounds without a single broken part. I do replace the recoil spring once a year. Apparently I got one of the good ones, I plan on shooting it for the rest of my life, and then my son can see if he can wear it out.
Paid the full retail price of 325.00 back then, best money I ever spent.
