I have seen several references to the screw grip including folks identifying it just from the external photo of the action. Please tell me or show me (even better) what a screw grip is and its virtues etc.

It's basically a third bite or "grip" that works off the top lever screw.

It was a Webley patent. Screw grip guns continued to be produced by Webley & Scott after they merged. Easy to identify. If you remove the barrels, you'll see the threads in the slot in the breech face (hence the name "screw grip") where they engage the rib extension.

1884 Webley & Brain patent. The action has a threaded spindle and a doll's head, a cross shaped doll's head or a simple step as a rib extension. the top lever bolts the step on the extension, providing a third grip (as well as the Purdey double under-bolt). Use by a huge number of gunmakers., usually built for the Trade by Webley/ & Scott. You will see it used extensively on double rifles by Army & Navy, Rigby, Atkin, Tolley etc and very commonly on boxlocks by William Evans, Army & Navy, and many others. It is a very good action, often made in very good quality. It is trickier to re-joint than actions without third bites. Look out for gaps at the top forward edge of the doll's head.

Jerry, the screwgrip action provided a very strong third bite and can be clearly seen in these photos of a Army & Navy (Webley). Hints that a gun is a screwgrip are the large diameter of the top lever head, the locking screw on the top lever screw, and the rib extension reaching all the way to the top lever.These are all characteristics of the action. Note the square threads on the spindle shaft--that's the screwgrip. (gun made in 1921)

I have one. Army & Navy from about 1890. Doll's head, fluid steel barrels, black powder proofs. Don't have the gun with me so this is the only photo I can post.

hello,
re the army and navy shown above,i have always understood the top extension style on the above gun is known as a spade extension,as opposed to a dolls head,which is round.(circular)
that is the terminology around my gun circle,but we could of course be wrong!
cheers
