In the archived Berkeley documents it lists these things as accessories:
Weed cutter hand hole cover. For operation in heavily weeded areas.
Finger grate to go with Weed Cutter.
Detachable trolling rudder with obstacle kick-up.

I'd like to see or find any of these items. I do see that the document set in particular was for a JA pump, would the above parts adapt to JC if they existed?

Anybody ever seen any of these?
