Guney,
I checked out your site, tried to comment on it yet I have no Google, Twitter or other account to start one on your site.
Wanted to say excellent model building going on & looking forward to stopping in again.
Back in 97' I had not returned to the hobby of model building, if I had there would be a LOT more DETAILED photographs of the converted Sherman tank.
Being a unique conversion a modeler can take assumptions on the assembly. Its basically a large post like on a ski lift with winches to hoist, winches to use as a live load line and anchor cables. There is large hydrolic reservoirs indicating hydrolics power the winches and may aid in hoisting the tower. Further examination hint a separate motor mounted to power said hydrolics, most likely in the large box or 'house' where the turret would roughly of been. Also the very large anchor plow or spade on the rear.
Thanks for stopping in to check out the beast!
