Roto replacement crank handles

A quick learner from New York says:
Hi. I am looking for replacement casement window crank handles. The hex portion has broken off several handles.I don't know the brand of windows since I rent my house. After researching, I believe the cranks I need are white Roto hex-spline, non-folding handles. The number imprinted on the handle underside is OP05-1509. I can email or text photos if necessary. Thank you!
