This 1914 Terni M91 long rifle is marked with the RE stock cartouche which is very unusual. ( RE = Regio Esercito or Royal Army) This is from one of the Italian Africa colonies between the wars.
Italian army troops were issued rifles so marked, and native levies had rifles marked AOI ( Italian East Africa ) or CAS ( Corpo Afro Somali).
This was an attempt to keep arms trading and theft to a minimum. Supposedly, if native troops were found with an RE rifle, they were either shot or hung on the spot... assuming there was a convenient telegrapg pole. The AOI & CAS rifles were not supposed to be traded around, either.
But given native ingenuity and a pressing need for goats or another wife, I have no doubt many found new homes contrary to what the Italians had in mind.
It's not mine. I bid big but didn't hit the reserve. I think that was my cue to move along to another auction!
