Those sights in the Ross article, are identical to the sights on Merkel double rifles of today! The sights are fine if the owner is a pistol shooter, because that is the type on most well made handguns, and if used properly, they work like a charm.

It is true they are not the best for dim light, and as the best place to have a double rifle, or a big bore bolt,is in the follow-up into the weeds with something that bits back, they should, IMO, be changed. I have two rifles, both double rifles, with this type of sights, and they will be modified to the wide "V", and the front Partridge re-formed into a round bead, and the face filed at an angle that reflects sky light back at the eye!

Ross S, is a knowledgable man, where old, or odd rifles are concerned, but I never read him much, unless he was writeing about something I was extremely interested in at the time. I find his writeing to have a little bit of an elitist tone, that doesn't set well with me! Still he is a person who knows his beans, and his advice in getting an unusual rifle to shoot well, should be taken to heart.
