M15 (F4) are the original 30 Worsdell engines of 1884-87 plus a further 130 built by J. & S.D. Holden in 1903-09 with 160 lb pressure and plain cab (coal 3 t 10 cwt, water 1200 gall), less 32 engines rebuilt from the Holden series between 1911-20
G69 (F6) are the 20 S.D. Holden locos built 1911-12 with 180 lb pressure and side-window cab (coal 3 tons, water 1450 gall)
M15 Rebuilt (F5) are the 30 rebuilds from M15 (F4), rebuilt 1911-20 with 180 lb boilers as per F6, but retaining original cab, tanks and bunker.
Two (GER nos. 789, 790) built as M15 (F4) differed following rebuilding in 1912: they were given a G69 (F6)-style side-window cab, but retained the M15 (F4)-style smaller tanks and larger bunker. The LNER mistakenly assigned these two to class F6 based on the cab shape, but they were reclassified F5 by BR based on the coal and water capacities. --
