I acquired an S54 Match this year. I gotta say, I instantly bonded with the thing; it's sheer eccentricity of design is weirdly irresistible! As luck would have it, mine is no. 4707 - the very gun that Tom Gaylord once owned, and wrote up on his blog:https://www.pyramydair.com/blog/2019/04/bsf-s54-match-rifle-part-5/If you have a Facebook account, a new special interest group, "BSF /Bavaria Airguns," has recently started. Some good stuff is posted there, including an excellent multi-part photo-illustrated writeup showing dismantling and repairing an S54.I hope you will post some shots of yours - and I will do the same. This forum would be the perfect place to expand knowledge of this fascinating and influential airgun manufacturer.
And more (due to attachment size limit):The supposedly-never-cleaned barrel was a chore to clean, given the taploader geometry - my usual patch pullers were impossible to use here. So, I loaded the BSF with four VFG felt pellets (two in the tap, two loaded from the muzzle) to give sufficient resistance. The pellets shown tell that cleaning was sorely needed.
Thanks, MarkYeah, it's obvious the BSF 54 isn't a speedster, nor should it be. Gaylord got around 715 fps / 9 fpe out of his 54, which is now owned by our own Mike Driskill. The cocking stroke of my 54 tells me the mainspring has fatigued quite a bit - there's little spring in the spring. Getting those missing 2 - 3 fpe back would make the gun a much better shooter.
Yeah, I remember reading how the diopter sight of the 54 Match isn't all that, and the gun doesn't shoot any more accurately with it than with the open sights. So I'm not too bummed I don't have the peep, apart from theoretical resale value down the line.
