Hi, I'm more confused than ever now. Is the round in the photo 47 or 57mm ? The fuze on my 47mm is marked up to 22, perhaps distance rather than time.(Surprised if 22sec.as only one time ring) It's identical to your picture. Your pictures from the manual show common pointed or H.E. shells in bottlenecked cases whereas my case is straight sided. and slightly shorter although it does have the tapered rim of the bottleneck cases. I'm still at a loss as to the correct size case for my Russian 47mm/3pdr. nose fuzed H.E. round .I think these are most likely for the Russian 47mm Hotchkiss revolver cannon used as fortification flanking guns, but manufactured by Nordenfelt, because at one point the Russians adopted 57mm Nordenfelt guns for their newer forts and they presumably switched ammunition production to the latter for their earlier guns as well.
The time fuze itself is definitely a Russian 8-sec fuze of a type I've seen on 57mm Russian Nordenfelt shrapnel shells and the case dimensions seem to fit with a few photos of plates for the 47mm Hotchkiss revolver guns from a Russian manual I picked up on a forum a few years back. Those have a nominal case lenght of 131.5mm.
