Window crank replacemeny

Hello,

This looks like an older version of the 39-091 and 39-092 Short-Arm Roto operators. They can use either the 39-224 Folding Handle or 39-230 Handle. 

Please note that the long bracket arm that connects the short arm of the operator to the window is no longer made. Unfortunately, Roto has discontinued a lot of the hardware used with these operators and there are no known replacements at this time. You will need to reuse your old bracket arm if possible. Take a look and thanks for posting.
