Pierre, In 7¼-inch gauge the scale ought to be 1:8. Prototype dimensions were: cylinders 16" x 22" wheel diameter 3ft 9.75ins boiler diameter 3ft 8ins boiler length 10ft 8ins Firebox length 3ft 9ins Grate area 10.75sq,ft. water capacity 600gals The above figures are taken from D.Bradley, LSWR Locomotives, the Adams Classes, (1985), p.97. The livery changed over the years (from 1891 until the end of steam on BR). Bradley's book has a chapter devoted to liveries. If you are in the UK you should be able to borrow this book from your public library. If not, let me know the particular time that you would wish your B4 to represent.
