The author of the article, Alberto De Carli, ask me to place his answer at this topic:
"I saw the topic of the IAAFORUM and I’m glad that some people like it.
I’ll translate it in english in the next future and it will be pubblished on the same web site.
I found the very early RN 1891 ammunitions at a gun show, maybe 3 or 4 years ago. These ammos were in a box with other cartridges and were not loaded in a maxim belt. But these cartridges surelly were loaded in the belt for a long time.
I put them in the Izvhesk clip.
My warmest regards,
Alberto De Carli, Italy."
