I know. I have 2 Redhead 12CVs, 1 15CV with pullstart, and 1 12LD currently in my possession. I have one better for you. I have the cooling head from some company that lets you use a turbo plug on your 12/15CV. I have four of those heads.
Now, if this stuff was for a RX 15 (which I have one as well), then you can say "rare".
