Help identify gy6

hello guys, Im looking at a new in box 152 qmb" gy6 engine for sale, the guy claims its a 150 but doesnt the mb identify it as 50? Is there a 150 with those letters in the model? Im not that familiar with scooter engines so any help would be great as I plan to look at it after work in a few hours.

Thanks!!!

Oh also, he claimed it was purchased for a customer, who has the paperwork so he can't show me exactly what it is other then by whats stamped into the metal. Just makes me nervous, not looking to get ripped off.

My 150cc engine reads 157QMJ. 152 sounds like a 125cc mill, but I thought the letters on those were QMI, not QMB. And you are right....the 50cc is designated as 139QMB.

The B would indicate that it's a 50cc....
