Gents I got the rifle back and all went swimmingly until I tried to put up a photo of the serial number. You have no idea how bad I am with computers and how much I hate them. I'm unable to upload the picture concerned.
Any way tested it back home slight recoil and felt heavier to cock than I assumed, tested it over the chrono with .177 superdomes and came out about 620 fps 7.2 ish Fpe. All good
I have tried to read the serial number but it seems slightly worn after cleaning carefully it looks like CS 14080. The letters show up well but the last number could be a 9
Does this make sense to you?
As for the paint it looks like there is a sliver layer beneath the black as I used my finger nail to tease off a few bits and the brown was beneath
Can you make an educated guess on which model it is and which year is was made.
I asked the auctioneer who was selling it and it was Albert Gunn's son ,now in his 70's. so I'm hoping it's in good knick.
One other thing would you try to get some neatsfoot oil onto the piston seal by pouring into the open transfer port, closing again and cocking to suck it in?
Thanks
Thomas
