Jalousie louver crank. No brand name found.

A home owner from St Louis, MO says:
Hi,
This crank is on a glass block basement window installed in the early to mid eighties. Any chance that a version of this that you sell would be a universal fit? Thank you.

The 39-005 operator is very popular with glass block manufacturers. Please compare it to what you have installed now to confirm if it's a match.
