Wish I had a couple of those catalogs now. I am not the original owner, was quite young when these were made, and knew nothing about them. The gentleman who I bought them from really knew his stuff and knew where to get it. But like many others he has passed away taking all that first hand knowledge with him. I have the paperwork for all the Beeman, Benjamin, Sheridan, and the rare Crosman pieces I got from that collection but these two rifles had everything but the paperwork, and it took some digging to find out where they came from. They each had scopes still in the box, one has an auto-loader, they both had real nice slings, silencers, and I'm pretty sure they have been tuned - but no info - no paper. They are the later issued models with the all metal triggers, longer stocks, and the MKII features (that I still haven't quite all figured out). They have been safe queens for some time now until I set up my little indoor shooting range. Been able to set up the chrono and play around some, it's been awhile since I have been able to do any shooting. The numbers get better every time I pull the trigger. These things are hungry to be used, doubt there has been more than 100 pellets through either of them. I am west coast / Oregon so I never get to any shows... Thanx for your reply, David
