<{POST_SNAPBACK}>Maybe because its late, but to me both drawings look very very similar.
What are the major differences?
To expand further, one design has a narrow firebox: pretty much the boiler of the standard five as BRITHO posted, the same sort of relationship that existed between the LMS Black 5 and 8F which had boilers of similar design and capacity.
The other is a wide firebox design, in an arrangement similar in concept to that on the 9F. But there the similarity ends, as it would have to be a completely new design of boiler: one approach would be to take the 'Clan' boiler and for modelling purposes 'trim the barrel and firebox depth to fit' much as the Brit boiler was cut down to suit the 9F.
But the BR 8F was never a real possibility, there being plenty of reasonably new Stanier 8F and the related WD design 2-8-0's available, and numbers of other 8 coupled types perfectly fit for many more years to cover their class of work in the antiquated technique then dominant: low speed mineral haulage in tiny loose coupled unbraked wagons. (As BR discovered when diesels were introduced and the extra power made higher speeds possible, all that meant was that derailments became much more common. BR then had to scrap (at last) most of the small unbraked loose coupled wagons, and introduce continuous braking in a hurry. You really couldn't make up a tale of greater ineptitude...)
