Looking for replacement crank for casement window.

Question

Handle on the small casement window just spins so need to replace entire crank system. Cannot identify part needed as there are no markings. Windows are Barber and Ross, a company that is now out of business so cannot determine what crank supplier they used. Thanks.

This looks a lot like our 39-083. Check it out and see what you think. You may also want to see our 39-140, which is a bit smaller. It's hard to make out the size of your operator, but check these two parts out and see what you think.
