Here's a few.

DC, Decontamination, white initials on black helmet?

Looks like something out of doctor who. Very nice and collectable, and rare.

Pictures?

Very nice.

They often come up on Australian ebay.

Helmet looks to be an BMB made one, date/maker name should be vertical to the rim at the rear inside, sometimes an imprint can be seen showing through on the outside.

Yes, it's an Mk3, rivet instead of an nut and bolt might be due to a couple of things. Nut and bolt got lost, and a quick repair done,WW2 or post?? Or maybe an Mk3 liner was added post war, as seen on the post war Mk4, but probably the first option.

These are WW2 British home front used helmets, I'm pretty sure for the thousands who worked in large factories. Very basic construction, no liner or nut and bolt, just rubber glued to the inside, chin straps either leather or webbing riveted to the helmet. The rim is called a Dutch bend where it is rolled under. Not to many around compared to a normal Mk2.

Here's a bit of info: The American M1917 helmet shells were pressed and stamped into bowl shapes by 7 company's they were. E.G.Budd. Manufaturing Co - Philadelphia - Pennsylvania. Sparks Withington Co - Jackson - Michigan. Crosby Co - Buffalo - New York. Bossett Corporation - Utica - New York. Columbian Enameling & Stamping Co - Terre Haute - Indiana. Worchester Pressed Steel Co - Worchester - Massachusetts. Benjamin Electric Co - Des Plaines - Illinois. The steel for the M1917 helmets was rolled by the American Sheet and Tin Plate Co and were stamped with a Heat No and Shipment No. The helmet liners were made by 10 Shoe Manufacturing Company's, the shells and liners would be delivered to the plant of Ford Motor Co of Philadelphia were they were painted and assembled. Known Heat Stamp Marks of M1917 shells. UC. YJ. ZA. ZB. ZC. ZD. ZE. ZF. ZH. ZJ. So ZC-305 thought to belong to Columbian Enameling & Stamping Co.

Quite often seen, a fake date put on an post war liner, which is a shame, as it is now not one thing or the other. On the rubber buffers of the liner which face the inside of the helmet, are there serial numbers on them?
