I'd like some info about these hub caps because our charity will sell them to help pay our expenses. Any help would be appreciated.

We have six of these.

I think they fit 1940s Colson Tricycle. Don't know exact year(s.) Any ideas? I recently saw a 1937 Colson trike, looked like these hubcaps.
They all have a removable drive plate, drive hub (correct name?)
Drive plate is held in with the spring shown.
Drive plates all have a slotted crown nut on one side.
Five of the plates are cone shaped on the other side and one is flat as shown in photos.
All have a right hand 7/16-20 thread.
Some were marked L.H.Colson trike, so I assume that all of them are for the left wheel.
I'm guessing that right wheel plates would have a left hand thread.

Of course, if anyone can suggest value it would help us immensely.

I think your best bet is to auction them on ebay. But given the rarity of the trike itself I cannot see these parts getting much attention, but it only takes a couple of people needing them to get a good price.
