Carrier armour manufacturer?

David, British carriers used armour plate that looks like the smooth pattern you might see on sand that is levelled by gentle water action. A fine ripple pattern that was easily hidden by a coat of paint.
The Australians I believe developed their own bullet proof plate (BP2) As i recall production was held up for a while with welding it. I think stainless rods were at least the interim fix. I think the need for stainless rods was overcome during the Australian and New Zealand carrier production. Hopefully someone more in tune with Aust. pattern carriers can verify this.
My British built and welded hull AOP carrier (mid 41) was welded with stainless rods.
The un answered question I have is that some British built armour, (the heavy daimlier armoured car as an example) is made with the Canadian style "axe marked" armour plate. How did this come about? Was Canadian plate supplied to British industry?

Hi Lynn,
After many years of being around British armour, I have noticed that those plates on Daimler hulls, Dingo scout car, Armoured Car and Ferrets, that have a cut out for a flap or visor, etc are those most likely to have the hammer marks. This I believe is because the plates were machined and cut before the hardening process and some distortion may have occurred. The plain plates with no cut outs do not seem to have the marks, generally.

The welding was done with Nickel Chrome rods, although stainless may have been used in later repairs. The process of welding armour was pioneered by Guy Motors for their armoured car, but this vehicle was later produced by Humber.

Nothing to do with Canadian steel manufacturers or lumberjacks wielding axes!
