I almost finised my "new project", but your model looks a lot better!!
I don't need the "2 men" part of the kit, so if you want I can send these to you (but you have to paint them yourself)
I have had measurements made and sent various figures to two different people/companies to make a 16H and or Big 4 model.
Unfortunately neither of them have been forthcoming with models until now.
Most frustrating.
Revell used to make very good models of BMW R75 and Zündapp as well as I think Triumph 3HW but that was years ago.
They were also in a better size scale.
