Hi Marcos
First , I realy like your models and the choice of more exotic vehicles.
I have a copy of a manual concerning this Balloon winch,
showing the whole construction in detail + some pictures of the
vehicles used.
I also have some pictures of the actual vehicle, taken at Beltring - England some years ago
Contact me off-line how I can get them to you.
Regards.
