Friends of mine (actually, their father ) had an MF25, back in the early 70s (and a Lambourn cabbed DB990). They got serious stick at school (the school JamesF and Nashmach went to) over the MF25 - nobody believed there was such a thing, they were that rare in this part of the world. People travelled from miles around to see it
The 25 got replaced with a DB780, the DB990 with a DB996, the DB780 with a DB1210, and the DB996 with a Massey 390.
What goes around comes around!
(The closest they ever got to a blue was a Muir-Hill 121 - and I have a vague recollection of a borrowed 6X 5000 buckraking silage once upon a time)
