I got a book by an Arthur E Carden which explores the Cardens of Templemore. He has a bit of info about Cardin which I didn't know, but leaves me with a question. He reprints a letter sent from Carden to Loyd about progress of various endeavours (inc A9, A10 & A11). The thing I can't decipher, is the use of the 'm/c' or 'M/c' abbreviation. I don't know if an engineer would have an idea of what it is short for. The problem is that it is used in, what seems to me, to be different contexts, referring to engines and guns, and being me, I just can't sort it out.
Letter written 7 Dec 1935.
Quote: "Price is the only trouble and I hope the new V.8. m/c will get over this - the only trouble is that it keeps getting more expensive."
2nd quote: "The new V.8. M/c has already completed its trials at M.E.E and is now with a unit." It has not got quite the performance of the old M/c but it is thought good enough."
3rd quote (possibly in reference to Universal carrier, according to footnote): "It is not so roomy as the old m/c but it carries all the W.O (War Office) want."
4th Quote (and goes to the gun on my A11): A big success is our new 40.mm Gun fitted in Light Tank. The turret is not very nicely arranged yet, but is being modified. I went to Elswick last week and fixed it personally - it is no worse to handle than a m/c gun, the kick does not even effect the tank and the personnel - but it is a hell of a gun - it goes through 2" plate at 700 yards like butter. Any country having light tanks so fitted working in pairs with similar machines with m/c guns could easily hold up any enemy whether they had tanks or not."
Interestingly, regarding the 40mm gun in a light tank, which dates around 35/36, David Fletcher's Mechanised Force, both the Latvian and Vickers Command Tank, the gun was 'a quick-firing, semi-automatic weapon it was described as Vickers own design and claimed to have a performance only slightly inferior to the 2-pdr anti-tank gun of the same calibre developed by the Royal Arsenal.' I think Vickers and Royal Arsenal competed for the 2-pdr gun order, which Royal Arsenal won, but Vickers produced some of their own. If that is the 'm/c' gun in the attached sketch by Carden, then it might not have been the naval 2-pdr pompom but the semi-automatic Vickers gun.
Anyway 'm/c' or 'M/c': any ideas?
