Definately a model 8 as Blumbly has Stated,also with correct serial.
It should be the early 125cc with port covers.
BAD as I had always assumed was model 8 and early sheerline 6 by the many examples Ive documented.
Recently we have had a few BAD serial examples on model 5 S2 mowers, Yours and VMans, and with the same earlier stamping style of the last model 5S2s, things became a little confusing.
I now am reverting back to this Serial sequence as being Sheerline Era only as Id always assumed to be correct from my research examples...
So Yours and VMans BAD engines are not correct fittment for your model 5S2 Mowers....
