I was told by Crosman that without barrel band & the stamped steel trigger guard, I do indeed have the Variant one model 160, 1955-56. No hole, no spacer, since none of that was used on variant one, according to them. Save for the screw with the toothed washer that goes through the base of the receiver cut-out in the end of the barrel. That uses a tube-like seal where it goes into the gas tube between the receiver & Co2 gas tube. I did save all the parts you sent me, Mike. Thanks for asking.
And the boys didn't follow my instructions to send the box Priority, but sent it " first class domestic", & they say it'll be there this Friday, 1/27/17. And Ziabeam, I messaged you the tracking number & such. I've read/heard from archer that they can increase it to 750FPS with the paint ball bottle mod. But that always looks to me like a 180/QB stock was used for that modification. More Muzzle velocity would definitely be an improvement. I personally do not at all think that paint ball bottle is needed. Just use the two 12g Co2 powerlets & wouldn't mind decreasing shot count from 50 or so down to 30-40 shots. So you're welcome to make whatever flow improvements you can to the valve assembly. Here's another idea I discussed on Facebook air rifle pages. Look at the end of the long part of the valve where the white seal is (new seal from Mike, btw). See that dished out area? It works like the dished area of a piston dome in an engine. So machining, say .002" off on one side, actually giving .004", being a circle, would slightly increase the actual amount of Co2 being compressed the way the end of the gas valve works.
And yeah, I did put in a couple months, while taking extra time to record it on Youtube videos, to restore the rifle. Went over everything in the rifle. I will definitely be posting some videos of sighting in-shooting it at the range, if they permit it? I really have to give thanks to you, Mike & all the others that offered advice on this project. Having shot one that belonged to a family friend as a teen (this one?), I'm really excited to shoot it once more! * Saved the link you gave as well, Mike. That'll come in handy, I'm sure. By the way, what lube would be best on the valve assembly, hammer/cocking pistons, etc when I reassemble it?
