the lifter on the right i believe is the first version, the lifter on the left looks like the lifter used with #43 dragon wheels. also sharing the chrome interior :)

I wonder why Lesney went to the trouble of designing 2 different lifters???
They could share parts and save on tool creation as they did with the 59/73 Mercury baseplates
