Trade Stimulator Handle Needed

[WoodrailFanatic]

I picked up a cool little trade stimulator recently. It is missing a handle and I was wondering if any of you guys might be able to supply me a replacement. Willing to consider anything that might work if I can't find the exact handle. The handle needs to be pushed down to start the game and pushed down and released with a snap to launch each of the 10 balls.

The same company made Zipper and Zipper Skill. Zig Zag is made by another company but is obviously the same design...they probably bought Binks at some point or licensed the design.

Pics below. First two are of my game. The last pic shows a handle on a Zig Zag.

FYI the diameter of the shaft the handle needs to go on is .4 inches.

Thanks for your help.
