Can anyone advise me please - were there twin power versions of both the MH 101 and 102 tractors?

I came across a strange tractor at a show yesterday.  It was badged as a 101, it had all the twinn power assembly/mecahnism, yet was a gas/kerosene tractor with a definite 101 serial number that fell into the 102 serial number range (according to KO's data book).

I had previously thought that only gas tractors were twin powers but maybe this was a wrong assumption????  Or could it be something to do with this being an import to the UK???  I am also aware that there were many confusions in the wartime MH tractor range!!
