This is my second post. I have another helmet for your comments.
Its an Italian M33 that is finished in its original Royal Italian Army Grey-Green both inside and out. The outside however has had some additional lighter green camo effect sprayed on. It has had this for some time as there is rust bleed through to both colours of paint on the exterior (this is particularly visable arround the front Anchir stencil). It has the Grey-Green leather chin-strap. and the 'Z' stitched liner with 8 prong vent rivets.
It has a large Anchor stenciled on the front. Rust has bled through the paint finish on the front but not where the paint was thicker on the stencil.
There is a stenciled Tri-colour to the right hand side.
In my opinion this is a nice aged piece with nothing that appears suspicious.
Does anyone know what unit ? San Marco perhaps ?
