Silver, the intercepting sears are hanging from the screw/pin at the top of the action. Their purpose as I understan it is to keep the hammer(s) from falling if the gun were to be dropped etc. The trigger must raise both sear noses in order for the hammer to fall. Many very fine shotguns have been manufactured without intercepting sears but it's a nice saftey feature all the same.
I use lacquer thinner to remove old varnish/hardened oil. There may be other better ways to do it but I always have lacquer close at hand so that's what I use.
Ken, could you, when you have a moment, email me a copy of your data sheet for Dalys. I lost the one you sent me a few years back in a computer swap. I'm fairly certain you don't have this one in your database because I don't think it has seen the light of day in over thirty years.
