We thought we were buying a Golden Jubilee, but now question this since it has the regular badge emblem of the NAA and not the Golden Jubilee badge. I'm trying to determine the SN as well. There is a number on the left side of the engine, NAA93995. There is also a number on the right side of the transmission hump (the bubble?), NAA-7006 B. Can anyone help with this? Thanks in advance!
