I bought all my rollers from a good friend who imported a bunch of them in the past. I talked him out of the 500/450 No.1.

Thanks

That Carl Gustav is the rifle I used to do all the load development and testing for the 8x58RD over on Gunboards a few years back.

That Brevet Nagant stamp was a bit unexpected, but only so because Leon Nagant was well known in Sweden for the Swedish Nagant 7.5 mm Revolver m/1887 ( (You need to Login or Register to view media files and links)). Did not know about Nagant's Remington license to build rollers.

What were the improvements Nagants made to Remington rollers?

Thanks,

If you go back a few pages, you will notice a "Brevet Remington" and a number on the left side of the receiver. This is  the royalties number applied to every Nagant made Rolling Block to pay back Remington on their patent right.
One of the improvement was the breech. (hence the patent mark here). It may look similar to the late Danish and Swedish ones, but the firing ping indicator was specific to Nagant made arms (and patented).

A friend of mine has documented other differences between Nagant made RB (specifically a Papal state model) and Remington made arms (Egyptian, greek) and swedish (Husqvarna 1867), but I could not cite them from memory. (apart the fact that the quality of realisation and the quality or treatment of the steel employed by Nagant appeard vastly superior)

Is this improvement "It may look similar to the late Danish and Swedish ones, but the firing pin indicator was specific to Nagant made arms (and patented)." the firing pin retracter that is on the 8X58RD chambered Swedish rollers? Looks like same to me in posted pics.

Your sentence "(apart the fact that the quality of realisation and the quality or treatment of the steel employed by Nagant appeard vastly superior)" causes me to ask if Nagant improvements to steel were incorporated into the 8X58RD Swedish rollers?

Thanks!

In English-language info about Swedish rollers 67/89 there is little apparently reliable information about the re heat treated process. There are even assertations that the re heat treating "crystallized" the steel so much the receivers were subject to catastrophic failure -- something that appears not to have been happening. Instead, these 8X58RD chambered rollers seem quite adequate to handle the lower chamber pressures that military and commercial ammo, loaded specifically for these rifles (NOT the higher pressure ammo for Norsk Krag  & Dansk Steyer turnbolts). Smokepole50 and others in USA have provided very useful pressure test data for Norma 8X58RD ammo and some very useful pressure data for a few handloads -- all published in GunBoards webbsite for Swedish Military Firearms.

Years ago I contacted Swedish Royal Library in Stockholm in a search for documents reporting acceptance and other qualifying testing of these 8X58RD rollers. A nice report on the acceptance field testing was found but nothing more. 

SO, now that you have brought Leon Nagant's extensive involvement with Swedish rollers to our attention, we want to know everything that he contributed to their development. 

Thank you for your rather unexpected contributions!!
