Onondaga Metal Shops Fern Dish

This fern dish was produced Onondaga Metal Shops (signed OMS). Retains its original patina and is in  good condition. Two of the photos show a “234” written on the side which I believe was done in an oil or wax pencil and not removed when the piece was originally patinated. This could be the model number. Stands 4 3/8″ tall and the bowl is 8 3/4″ in diameter. The four legs protrude approximately 2″ ‘s each.
