Being a sucker for "old stuff" I purchased these two old bronze winches on eBay.

But they did not have a handle. Clearly they need a rectangular bar with handle to fit in the slots, but it's not clear how the original handle would have been held in place. I have seen pictures of winches that have a spring-loaded plunger in the centre that would hold a handle in place, but there is no such arrangement on these...
Rather than try to invent something, I wondered if the experts here might be able to provide a hint as to how these were designed...
thank you...
