to me looks like a model 5 series 3 as it has no edger slot and the same as the series 2 with no extensions on the base or axel housings, and the engine number looks about right from what I have read, and is similar to the number on my series 3 probably 59-60 model. she rough but by the time every thing is blasted and cleaned they all turn out the same, the engine is going to require a lot of work though.
cheers.
