And they are RARE handles to boot, no reproductions, and even though they LOOK the same as the pull-down side door handles, they won't swap. In an era when they used as many common parts throughout the line as possible, it's odd that they made an "odd ball" handle. Later model panels had the push button handles flipped 90 degrees.
I had mine restored by a chrome place that was good with repairing pot metal, but it still droops. This is mostly a case of the square peg on the handle rounding over with wear and the hole in the lock mechanism doing the same. The repair springs offered for the side door handles don't fix the barn door handle droop.
