copper-alloy Type \'A\' sheath

[Crispvs]

Lvcivs,

Thank you very much for bringing this to my attention. It appears to be a standard type 'A' sheath with, as Lucius Avitianus says, normal type 'A' suspension loops and suspension rings (the rings on Peronis' sheath are of type 'B' and are attached with hinge blocks rather than suspension loops). It looks from your pictures to be undecorated as well, which, if true, would make it only the third undecorated type 'A' sheath I am aware of. I wonder, do you have a good close up of the terminal expansion? Also, do you know what the brown corrosive layers are? It looks, from your first photo to be iron oxide (rust), but in the close up of the suspension rings it appears to be a condition of the copper alloy. I do not know enough about copper alloys to be able to make sense of this on my own.
Also, any idea of when it was found (and published)?

Thanks again for showing us this sheath! A laud point is hereby gratefully awarded.
