Incidentally, one of the older demountables -- I think it was the DEC

I did notice that the air filter on the RL02 was suspiciously similar in
size to the air filter for a Citro?n AX diesel. it's the right width,
anyway - you'd chop it down and lose the rubber seal off one side. You
could bodge that with RTV silicone.
