SteadyRig make. Compatible and identical to PRO. Serviced the same as PRO.
Good condition. Great for anyone making a low cost rig that can handle 35mm.
SteadyRig is from Hugo Langer who everyone knows makes great gear.
I upgraded to a 2" post and no longer need it.
-there's alot of pics of the gear in action on my website.
