Looking for info about m52t SPH

Hi everybody,
I am looking for all possible information regarding m52T 155 mm SPH. The Turkish improvement of the obsolete US m52.
The vehicle drawings and photos of the upper parts of the hull and the turret are most wanted. As well as photos of the rear spade of SPH.
And I wonder how they managed to room that big gun’s recoil system inside the turret? Was that a newly developed system or they used the one from other SPH?
All info will be highly appreciated!

Some general informations from the internet.
Some pics on Google.
Sorry, no drawings found,
