Casement window crank

Thanks for writing in. This looks like an older version of the 39-092 ROTO Short-Arm Operator. Unfortunately ROTO discontinued the bracket arm that connects this operator to the window sash, so you will need to reuse your old one if possible. For a compatible crank handle see the 39-224. Let me know if you have any questions. 

Could you be referring to the hinge? If so, we don't sell this exact model, but you may be able to use our 36-048 as an alternative. Just note that you have to replace both the top and bottom at the same time. Additionally, you may need to drill new holes, so keep that in mind.

As for the lock, this is also an older and discontinued part. However you may be able to use either our 38-095 or 38-096 as an alternative. Review the dimensions for both to determine which--if either--would be the better option.
