Ok, 95 with 1-piece trigger (should also have round loading hole on top and spot-welded steel front sight).
Seals, as you probably already know, are the same as a model 25, and are still available from Daisy.
The original shot tube can be replaced with the spring-loaded type (also made for the 25, but will fit the 95, just a little long), I have several, and they are more accurate and faster than the original.
cobalt327 posted somewhere that after a thorough cleaning he seats the abutment seal with E6000 adhesive. I’ve done this to several and have never had a problem, I will add that I use a 3/4” dowel and a long bar clamp to apply LIGHT pressure and let it set up overnight.
When this stuff cures, it’s like the glue they use to put labels on cans & stuff…just don’t overdo it.
One possibility for the bb’s is they might have tried to use them as a spacer if they put the stake marks in the wrong place, to keep from tearing up the plunger head (if so, it didn’t work). But for sure, they are either there intentionally, or as a result of sloppy assembly…there is no other way for this to happen.
Anyway, best of luck with yours ! These old wide-body models are a lot of fun, and there are a lot of mods and hacks you can do to improve fit and performance, from power and accuracy, to trigger and lever function, sights, and you-name-it, everything else !
Have fun and be safe !
