From an 1892 London makers catalogue:

My semi-hammerless double grip action special gun. This is an excellent gun for keepers and emigrants, its quality, style and performance is far in advance of any other gun of its class.

This gun (the line drawing shows it with rebounding hammers and a Jones under-lever) was for sale at 7 guineas. There is the Emigrants Outfit which includes:

The above gun, fitted with waterproof case - 1. Complete set of strong fittings for loading, recapping, reloading cartridges and cleaning - 1/7/0. 200 best cartridge cases, 2 lbs felt wads, 1000 card ditto and 500 caps to recap - 0/10/0. The lot complete - 10!

This gun was his cheapest own name offering.

Next up was this:

My new model top lever semi-hammerless special gun. Available for 10 guineas, there is no suggestion for whom the gun might be suitable! (The line drawing shows a hammer gun)

Then moving up again was this:

Body patent special hammerless gun Available at 13/10/0 for the plain version or up to 35 with very best Damascus barrels, ejectors 5 extra. (The line drawing shows an A&D action)

The best quality top lever, bar action guns with Whitworth steel barrels were available at 45 with 5 extra for ejectors.

On a separate page listing all guns that can be supplied, the lowest price is for a 12 bore suitable for use at sea, or rough work at 5.
