I am an old school guy beginning with my first handgun purchase in 1969 with a Ruger Super Single-Six which I still use regularly and still have the box and papers. As I said, I'm old.
You still have a 1969 Ruger Super Single-Six?!?
For your information, the man that my wife works for had one that he bought for $30 when he was in junior college (i.e. a long time ago!). He brought it to the range with me, but was having problems getting the cartridges in and out of it. I asked him when the last time was that he had cleaned it.
It turned out that he never had! So....I offered to clean it for him.
While doing a safety check on it, I found that Ruger had an offer to install a hammer block in their old revolvers.
I got him to do the paperwork to send it in for the modification. They responded back that they didn't have any
parts to update a revolver that old, so they offered him a choice of TWO (2) *NEW* revolvers!!
He chose a stainless one and is quite happy with it.
As a result though of my offer, he has sent me a number of guns to clean: an old 25 ACP FIE Titan, a 12 gauge Chinese-made pump shotgun and both of his son's Remington shotguns, the older of which looked like it had never been cleaned!
Working on/cleaning other people's guns helps my education toward becoming a gunsmith in retirement, which is only a few years away.
