Pics of my 3 South African market gunsights

Top - Percussion Evans
Middle -WR Monkeytail sporter
Bottom - WR 12bore x .577/450 cartridge

Note the adjustable ladder sight on the Monkeytail, driftable as Huvius states
With a most optimistic 1500 yards!!

Cape guns/rifles were popular in Africa, the .450 to .500 would drop any game at a pinch
the shotgun for other game/food

With the advent of cartridge rifles percussion was obsolete (Not entirely, hence the popularity of the Monkeytail) so many/most gunmakers offered conversions, especially to shotguns as 12/13 bores, 10 to 8 bores and 6 to 4 bores etc simpler to do than a rifled barrel, although I have seen a couple in .500 BPE

The usual signs, particularly the patchbox in the stock Jones lever )Lever over guard) as well as odd bits on the engraving

I have a WW Greener converted 4 bore goose gun (marked as such)

I would love to know exactly how it was done, a hooked breech helps i suppose

These early hammer rifles are my favourite and would grab yours (if in the UK) in an instant at that price
