We need to replace 2 window cranks. One is a left side crank and the other is a right side crank. There are not a lot of markings, however Del Mar is inscribed on one of the parts, and there is a number 31538A on the arm of the right side window crank. We moved into our house 5 years ago and these were already in the house. I am unsure of how old they are. Any help in identifying these would be appreciated so that we can open and close our windows with ease!
