Hello there. Just joined the forum, I've lurked here for a while and figured what the heck, might as well join in the fun. Any how, I have a 631 that has been home tuned and a 618 that was given to me by a co-worker. It didn't work when I got it, probably why it was free. But after some work it shoots quite well, I don't know how old it is. Maybe someone here can help me figure it out? Only markings on the gun are on the under side of the stock just behind the pistol grip-R114614S. It also has a short dovetail cut at the rear of the reciever.
I also have a freinds 624 that he wanted me to fix, it wouldn't push a pellet out of the barrel and needed a new piston seal. It works fine now, it seems a little newer than my 618 and has the numbers: 296641 stamped on the breach block. Can anyone here help me with the age of these guns? TIA, Mulby.
