Good afternoon, I have recently acquired 2 BSA Light pattern air rifle, the first of which I stripped, cleaned and fitted a new breech seal, all good, a little low on power, running around 4ft/lbs this i expect to increase a little as the seal beds in. for your information this is in 177, has a 2 hole trigger block serial number L11100 which i have been informed dates it to 1920.
The second, also in 177, having a 3 hole trigger block serial number L3777 has had the same treatment as the first, but without doubt will need a new spring fitting. this gun is also in extremely good condition, no real wear anywhere other than the front of the rear cocking lever where it pushes the piston back. so much so that it does not travel far enough to cock the gun. i have read most of the forums regarding these guns but have yet to find anyone mentioning the same problem. i am planning on getting this rectified by adding some weld to the worn area, then reshaping it by hand to the correct profile. it only needs about 20 thou.
Once i work out how to add pictures on here i will post some.

See my reply to your question about the spring.
Wear to the piston slot or cocking link nose where it bears on the piston certainly does happen and adding weld is a good way to remedy it.
See the technical tips section of this forum for advice on cocking problems from experts:

Thanks again, I swapped secondary levers over and the problem moved to the other gun, it is clearly worn, so i will build it up with weld only about 1mm and refinish.
