visual differences

i've found a good deal on a charger, but i need to know what i'm looking for. the i.d tag is missing, the guy say's it's a s-trim. but how do i tell if it's a a,b, or s-trim for sure. it does have a 8-rib pulley if that helps

I don't know the answer to that, but if its missing the tag, and you don't know the person selling the blower personally, walk away. This could be a bad deal.
