    An 8F boiler is, actually a bigger diameter than a Class 5 , normal boiler plate rather than nickel steel used on the Class 5s.
    The lengths of the taper barrel section were identical, but, as LMS 2968 says, the parallel barrel was 1 foot shorter on the 8Fs.

    That was, I believe, the plan for 44901, I vaguely recall another import was mooted, but it never happened?

    I was really wondering if there was a spare boiler to be had, rather than another loco.

    The boiler drawings are very interesting and the differences look to be very subtle for the most part. I wouldn't have thought it would be too difficult to make a hybrid 8F firebox and Class 5-like barrel, any sight differences (and we seem to be talking small fractions of an inch, so probably barely [if at all] visible to the naked eye) would be hidden by the cladding. And as we're frequently reminded, virtually no two Black 5 boilers seem to be the same anyway! Presumably the same was true of the 8Fs, with them coming from so many different builders. It would be interesting to know if some variations were closer than others.
