Here is picture of the 8ga falling block we are working
on, partly done. It is built like the 4bore one in a
one piece stock. IT is built .150" narrower than 4bore.
We used the heavy 8ga barrel that I first
put in the Enfield bolt gun for a 8ga testing. The breech
block, linkage, lever, pivot is done, as you can see
in picture with lever open and breech down.
I have got to chamber, put in firing pin, do
hammer and trigger. 8ga gun in 1st picture.

Hammer and trigger setup is now mounted and moves
on the back of the breech block on an extension.
I also made this change first on 4bore, 2nd pic.
It uses NEF hammer and spring and Stevens trigger.
Breech block set up same as 4bore just narrower.
Later hope to do a 2 bore and same setup only
breech and action a little wider.Ed
