Ive come across a few BAD serials lately, but ive not seen enough to determine their correct order or pattern.
However the Stamping is of the original early style and most of the other examples ive seen are on Model 5 series 2 mowers.
So since the model 3 and dep stores used the finer stamping, Id say this would almost certainly be mid to late M5 S2....But I cant be 100% sure until a few more examples come along.
The rest of the M4/5 Serial range is fairly accurate at present, with just a few unkowns remaining....
Just curious....Did this BAD engine come with this mower sale or is it one you already had? If it was with this mower then id definately say its the original....
