I'm just showing off again.
I scored a Mk.I spike bayonet on FleaBay, me happy
, I've been looking for one for quite some time. They don't seem to be that common.
Questions; Why was the design changed? Was it too expensive to make, or was it changed by political pressure to be a kinder, nicer way of stabbing the enemy? I have to admit, that little spike is a nasty looking thing, especialy on the end of a rifle, very surgical and business like, designed to do but one thing (They don't like it up em!).
So from what I can gather, the cruciform bayonet was the origial design issued with the first No.4s. I have heard all kinds of stories about the X blade making a sucking wound that won't stop bleeding. It was banned under some international convention. I heard that they are like blood grooves.
I think it is just to make the blade lighter. But the Mk.II is less time consuming to make with its solid spike, so I believe it was discontinued for reasons of economics.
Mk.II* is a design that was produced to allow the bayonet to be made in two pieces, ie blade and socket seperate and then joined. This allowed different machines and processes to be used, processes that were available in many industrial factories. A major boost to production during war time.
The Mk.III is a further concession to manufacturing processes. It is made up in several pieces, some stamped and then made into a weld assembly. The Mk.III was the last spike bayo for the N0.4.
Plonk attached (if it works) Mk.I, Mk.II, mk.II* and Mk.III
