I am looking for advice on selling some pioneer era African firearms that I own, and am looking for Advice on Values

1) Winchester 44-40- fairly early model Serial Number filed off (used in the 1896 rebellion by the rebels I would think. The Native police deserted taking their new Winchesters with them. European Police had Lee -Metfords) Rifle in good condition and shoots well.

2) Webley 1876 Army Revolver, Cal .476. This was the standard issue of the Pioneer corps when they first occupied what is now Zimbabwe. Fairly rare and you seldom see them in English Catalouges. Looks like a Colt SAA with a birds head grip, but is Double Action. Was issued to my Great Grandfather in 1889 (W. Ross, the Engineer to the Pioneer corps was actually born in America!)

3) W. Ross' Issue Martini Henry .577/.450 Rifle. A Mark II made in 1876. In good condition and a fine shooter. Has both B.S.A. Co markings and later Southern Rhodesia Markings when it was "sold" back to my great Grandfather.

Any advice would be appreciated.
