I tried the Daisy Match Grade Avanti BBs, the MV increased by ~10 fps, average was 324 fps, ES was 3 fps. I was able to tweak the rear sight to get the windage correct. I'm glad I didn't need to resort to anything more involved. It looks like the gun had been dropped or the rear sight snagged on something. The lever was too loose, I found it to be worn where the receiver pinches it, so I substituted the original Model 95 lever for the straight metal lever from the Model 104. It wasn't being used because the 104 has a Red Ryder buttstock and curved metal lever. Anyone got any ideas in the following? When did daisy start using phillips head screws? When did scope holes start/stop? When did rubber seals start, leather end? When did lever pivot change? When did shot change from lead to steel? What model(s) had strongest spring/highest velocity? I'm starting to think at least one model that used an uber strong spring was the cock-on-closing Number 3 Model 27 from the late '20s- early '30s, that used lead shot. In the diagram below, the spring is shown to have about 25 coils and elsewhere this gun was said to be a beast as far as power goes. So I'm wondering if the $25.00 spring I saw on Gun Broker might not have come from this, or a similar gun. The spring spec's were: 0.095” wire diameter 0.720” spring OD 7-7/8” free length 25 coils Extra points for: A description or diagram showing how the cock-on-closing mechanism worked. What other models cocked when closing the lever?
