Need interior door handles for a Tucker 543A

I am having a heck of a time finding a set of compatible interior door handle pulls for my Tucker. Anybody out there have any ideas? This is the round 20 toothed style held in with a screw and I need all three. The toothed hole looks to be about 1/2 inch.

Any help would be greatly appreciated!

Those look like the ones I've had on my Tuckers...

I think they were made by the A.L. Hansen Manufacturing Company, but I don't think the handles are still available. You might try contacting them as they may have a suggestion as to what would be your best option. Here's a link:

If the new (or replacement) handles aren't acceptable I'd consider drilling a hole through the handle and the splined shaft and then installing a roll pin.

You'd want to get the placement and alignment right so it should be done in a drill press or milling machine for best results.
