The arm has a single hinge and works fine.
It's weight range is 33-54lbs which makes it a good spring arm.
It's seen very little use over the years and is in very good shape.
Yes I have the covers I just took them off to show you the insides.
Robert Luna can put on the double hinge if you want for $1900.
He estimates the arm is worth $3500. now and $6500. with a double hinge.
My price as you see it $2,000.00 plus shipping.
So a huge deal for someone who needs a heavy duty arm.
Email or PM me to discuss.
I'd love to see it get some use and go onto many more shoots.
(It's not my personal, just one I picked up recently.)
