Damn those are testaments to their owners, can't be perichial but I'll vote for Phil's wee 350f, they are such honeys.
I'm kinda thinking there are some beautiful examples of so many models that a burn off between all the 4's is required.
350f vs 350f 400f v 400f and then it gets real interesting with all the 500/550 variants damn that would be a great comp.
Well done to the owners of such fine machinery anyway, even if you don't win here I bet you get the public attention vote.
