2108 white window crank

A home owner from Vermont says:
I need 2 of this part. The diameter of the window assembly barrel appears to be 7/32 of an inch and the diameter of the crank socket appear to be 11/32 of an inch. Can you tell what I need?

On the cranks that broke, the black plastic piece fell out, revealing a #1208 on the white metal piece.

Check out our 39-205, which has a spline size of 11/32". Could this work for you?
A home owner from Montpelier, Vt says:
The problem is the layperson like myself doesn't know what spline size refers to. Is that the same as the diameter of the socket on the handle?

Yes, 11/32" is the size of the socket in the handle.
