looking for replacement window crank

A landlord from Rochester says:

This is from the left side (looking in) of an old crank out kitchen window. I really hate to have to change the whole window and casing, so I am hoping you can help me. It is from a Crestline window with this number stamped on the bottom: 4-200LH. The arm extends approximately 9". The dimensions of the 'base' are 4"x2.5"x5/8" high. If you cannot find a replacement for me, could you please advise me of someplace that I might find it? Thank you so much for your help with this!
