I finished up my Pecatonica River "Lehigh County" rifle re-build today. I am pretty happy with it.
My challenge was to use as much of my original Pecatonica River
Lehigh County longrifle parts, (which I built in 1986) and re-use them on a
new Pecatonica Lehigh County stock. I re-used the Green Mountain .45 cal barrel, the lock, butt plate and side plate. The other parts just didn't make it so I bought new ones.
The original patchbox had a slightly wider lid, which I filed the butt plate for. However the new patch box lid is a bit narrower, so there is a little gap there.
I also could not get the old Durrs Egg lock apart and feared damaging it if I tried to force it, so I did my best to carve it into the stock as a unit. It was a chore but it turned out OK.
Rebuilding this rifle was pretty enjoyable. I will be shooting it in a few days, but first I want to work several more applications of boiled linseed oil into the stock, which is still pretty thirsty.
As I remember, and if the sights didn't move, this barrel is dead-on. Time will tell!
