Another recent pickup, from Brecon Militaria Fair. This is a good one in that it has a complete label! So theoretically we know everything about it. Except that we don't; I can find NO reference to this helmet anywhere.
It is badged as a COURTAULDS AEROSPACE AC700/450, and dated 1997. Courtaulds was effectively the predecessor company of what we know as NATIONAL PLASTICS AEROSPACE (NP Aerospace - home of the Mk6, 6A, 7, and most of the Para Lightweights, and lots of other helmets - now Morgan Composites ...pay attention!). I don't know this as a provable fact but observation tells me that the Courtaulds name was continued in use during the 1990s for a variety of export-oriented items, most notable what is better known as the Swedish Hjalm90. So it is possible that this was an export product.
It is a rather light helmet (910g, light even for a Small size), with a very basic liner, and I do wonder whether it might have been designed for sale to hot regions.
The plastic clip chinstrap fastener is unusual for Courtaulds/NP products. The front pad is fixed with velcro. It has a nape pad as part of the liner. It has a rather unusual design of plastic chin-cup.
The individual serial number of the helmet is 0005, which might mean that very few were made. Or it might mean the other 50,000 are in Myanmar....
I'm really quite baffled by this. It proves that having what seems like all the information doesn't always get you closer to the who where how and why of the thing. Any ideas?
