Hi all, the pictured rifle has Cogswell and Harrison Ltd. Bond St & Strand, London on the barrel.
It has a 24.5 inch barrel with folding leaf Express sights from 100, 200,& 300 yds with a long range ladder sight graduated up to 1000 yds. It has a Nitro Proved stamp on the barrel with BV, BP, NP proof stamps with crowns over them.
The charger bridge has a round notch in it to see the all of the sights.
The trigger guard and magazine are engraved as are all of the screws and around the screws.
The front sight is supposedly made out of platinum for high visibility, some of the Lee Speed rifles have this feature as well.
The forend cap is made from black horn and the grip cap is possibly the same material.
A tang safety is present in the photos and works well, the five shot magazine is engraved and the cutoff works perfectly.
The steel buttplate is engraved as is the trap door with engraving around the door as well as the screws being engraved.
The checkering is fine lined and not crushed, the wood appears to be a walnut variety, I'm not positive about which it is, perhaps others can identify the wood.
To top it all off, it's a numbers matching rifle with a very good bore.

PS, a quick email to Skennerton came back with the rifle showing a BSA&Co Patent 28834/97, he said it was made between 1898 and 1903, then he made a plug to buy his book, I think I will, John :}
