Portugal bought about 50,000 of these in 1886. Most wound up in the colonies and were used against the Jap. army in WW2 - as recently as the 60s in some of the colonial independence squabbles. Nearly all are actual combat vets. Closely inspect the muzzle ring - you will likely see evidence of a bayonet having been mounted.
Ammo is a hand load proposition only. I gnashed my teeth and sprung for RCBS dies so I could form 348 brass into 8x60R. I use the same Lee bullet as I do for M.95 = .329 and it works just fine. I have a starting load listed in the reloader forum.
Pricewise, I'd say between 250 & 350. More if all matching as the bolts seldom match. I think they were stored separately. I gave right at 300 for both of mine.
There are 2 varieties - with & without a handguard. The latter is called the 'colonial model'. The hand guard was supposed to keep barrel heat from burning the shooter's fingers during a prolonged exchange.
Theses are very well made and FUN to shoot!
