A lot can be learned from a craft's nomenclature.
I would be very interested in learning some of the special terms used to describe doubleguns.

For example what do you call the rearmost pointy part of the forearm iron?

What do you call a trigger that has verticle lines carved into its front face.

What is the "water table"

What do you call the part of the barrel that attaches to the forearm?

Thank you
Lou

knuckle, serrated, action flats, forend lug

Thank you

Especially for the knuckle, which is not on the Hallowell list

Is that what that part is called! I always just called it the forend metal.

OK then
My Hollis has rebounding hammers, what does that mean
I looked in Bill Greeners book and couldn`t find it

Percussion gun hammers stayed down on the cap after firing. It kept the cap from flying back in the shooters face. These are non-rebounding locks.
When center fire guns arrived, gunmakers used existing locks. They quickly discovered that, in a center fire gun, non-rebounding locks had to be put on half-cock before closing the gun with live rounds. If you forget half-cock, you are closing the gun on "fixed" firing pins. It will go off. Not very safe.
Rebounding locks solved the problem. After firing the hammers bounce back a little and catch just enough to allow the firing pins some movement back into the action face.
I tend to stay away from non-rebounders. They are for the more advanced vintage shooter.

Thanks, That makes sense, Much appreciated

I think more definition is needed.

The receiver has a concave surface that engages the convex surface of the forearm iron. The forearm iron has a rearmost edge

What is the "knuckle"

What are the other parts called?

In my terminology which may not be strictly correct but serves its purpose, the entire joint of the forend iron's concave and action's convex surface is the 'knuckle'. Both parts form part of the knuckle so I would refer to them as the 'action knuckle' and the 'forend knuckle' meaning the metal in the immediate vicinity of that joint.
I am sure there is a more precise terminology but until someone publishes a definitive book on the subject....!
The London and Birmingham trade have different names for just about everything which is further complicated by the larger gunmaker's having their own peculiar terms.
All good clean fun!
