UBB.threads Forums Edged Weapons The BCN Bayonet Forum Grandfathers "PS" spiked bayonet (help identify)

Ok so most of my grandfathers souvenirs got taken long ago, but my dad gave me a bayonet that I cant identify. Its some type of folding spiked bayonet, maybe a mosin 44, maybe a french mas, Im not quite sure. Ill post pics in a bit but it has PS stamped up top on the flat part. I looked online and found 1 example just like mine on a forum but no one could identify it. Its semi triangular spike, has a flathead screw with a spring and a latch to attach to a gun. Still wicked sharp, blackish in color, and a little rusty. Any help would be most appropriated.

Here you go, PS is written where the last photo is but I doubt you can see it, anyone know what this bayonet is? I don't think its german.

Looks like Mannlicher-Carcano M1891, variant 3

hi north carolina
your italian model 1891 carcano as vat 69 post is 1,000 percent correct if any one has the 1891 carcano missing the folding bayonet bingo you have it. if im not mistaken italy updated thier 1891 model in 1938 not much difference in the 1938 model compared to the 1891 intresting best of luck thanks for showing this hard to find folding bayonet glad we could be of help to you god bless andy militarynut

Thank you very much for identifying it, I for the life of me couldnt figure out what it was. He wasnt in italy so he must have traded for it. Thanks!

Same opinion,Mannlicher Carcano cavalry carbine i saw similar on 1943 dated pieces.b.r.Andy

You think cleaning it would be a bad idea? Im pretty sure this one was out in the garage since about 1960 to 2015 having survived the eye of katrina and 2 trees crashung through the roof, i guess it gives it a little more history is all. 70 years of louisiana heat and humidity plus crossing an ocean and going through a war does tend to add some rust, but the blueing/paint seems to have held up rather well.

Soaking with diesel, then in arm oil and gently cleaning with soft 000 wool would preserve the origin blueing on mainly parts, or simple wishing and good oiling, that rust will not continue.b.r.Andy
