These are fixed turrets for gunnery training, 'fraid I can't remember the location.

Skip, Jersey seems to have examples of every French tank turret imaginable. We also were of the opinion that the one on that St. Ouens bunker was an H35 or R35 but the owner seemed to think it was originally fitted to an FT17, having seen his incredible collection we were loath to argue...
(If anyone finds themselves in Jersey the museum he's squeezed into the bunker below the turret is wonderful, I thought much more interesting than the much vaunted underground hospital... he can also sell you quite surprising German militaria from the back of a clothing shop in St. Helier ).

Cheers,
Adam.
