There were a few around when I was a kid, but the calendar sez that that is now a LONG time ago.
The 1905 model was made in 2 major versions, differing in the diameter of the hole for the barrel. Small ones are a lot scarcer than the more-common large ones. It is the type you will see, as it also fitted the 1910 rifle.
By far the majority of these would have ended up in Russia, along with the rifles. They got Rosses late in War One, again in War Two, plus all the ones they stole from Latvia.
As well, a lot of our guys "lost" the bayonets when the rifles were turned in, made them into trench knives. When you consider that they cost $5.50 apiece, those were expensive knives.
In short, they are not really RARE, but they are sure a LOT scarcer than you would think.
Good investment: somebody told me that they aren't making them any more.
Wonder why?
