I have a BSF Junior air rifle in .177 that I received from my Father as a birthday gift 50 years ago, while living in Germany. As you can expect, it is in need of a new seal, and possibly a mainspring change. Can anyone provide info on who might have the parts, or who can do the work? I live in the US, but don't think ordering the parts from another Country would be a big problem, if I can find them.

Then get some observations and measurements of the piston seal and spring, and go here: http://www.airrifleheadquarters.com/page/page/251327.htm It's possible that a gun of that age might even have a leather seal that can be rejuvinated. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Mon May 19, 2014 8:31 pm laelkhunter New Member Joined: 11 May 2014 Posts: 4 Thanks for the help, and the replies. jg advised he would not be able to help. Slavia- Yes, as far as I can tell from research, it does have a leather seal. Can that be brought back to life with some RWS Air Chamber Lube, or could I try another chamber lube of some type? I would be hesitant to try to take it apart myself, and haven't been too lucky finding anyone who would work on it.   Posted: Tue May 20, 2014 5:41 pm Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA Even non-detergent motor oil will work. It's hard to say what it's like without seeing it. It could still be oil-soaked and pliable, or it could be all dry and crumbly. If it does indeed have a leather seal then it needs oil as a matter of regular maintenance. What you may have read about high-powered springers dieseling and detonating combustible lubricants won't apply to a lower powered gun with a leather seal. (It may smoke a bit, though.) _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Tue May 20, 2014 6:04 pm laelkhunter New Member Joined: 11 May 2014 Posts: 4 Thanks Slavia, I have some of the RWS chamber I use on my RWS M34. Would you recommend the ND motor oil over that?   Posted: Tue May 20, 2014 9:44 pm Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA That should work fine. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Wed May 21, 2014 5:24 am laelkhunter New Member Joined: 11 May 2014 Posts: 4 Thank you !!   Posted: Wed May 21, 2014 5:23 pm Slavia Moderator Joined: 31 Mar 2008 Posts: 4382 Location: Waseca, Minnesota, USA Keep us posted on your progress.
