Pickaxe dimensions

[Lynn Eades]

Hanno, the two shown in your two photos are (obviously) different. The first is an American type, while the second is British (as found on carriers). The American pick heads come in different lengths (not sure about military ones), and I wonder if that is why the one on the back of the CMP is not sitting its end against the rub plate.
Interestingly I have a pick mount that takes (what I assume to be?) an American pick, but has a BSF thread on the stud.
The shorter (lower) one is from a Canadian U.C.
The longer (higher) one , I'd like to know its original application?
The Australian carrier used the American pick, but used Unified thread forms (plus BA for small stuff) So, i don't think its from there.

Btw, with the British helves, the early ones had a steel ring at the hand end (WWI) the later ones were plain. These were used through WWI and WWII.

Further: I've had a minor epiphany. I believe this was made to fit the carrier as well (same mounting) Maybe it was to do with supply of picks? I will be watching for carrier pictures with the U.S style pick from now on.
I had assumed that this was from An Australian pattern carrier, until I checked the thread of the stud.

Thanks Lynn,

I obviously have a lot to learn about pickaxes. I raised the dimension question as a friend of mine bought a few dozen and I am trying to help him sort them out. Obviously there are many detail differences because these are forged.

Bert found they are dimensionally different, apparently because the type used on vehicles was larger than the type carried by Infantry.

Most are marked with the British Broad Arrow, a date and manufacturer name. Bert thinks the helves may be US ones.

If anyone can point out the differences between US, British, Canadian, Australian and other? ones, we can add this the collective font of knowledge here on MLU Forum.
