I dug this out of the yard. First thought was a shotgun shell casing, however it’s actually some kind of cap or lid. I suspect something mechanical or industrial in nature due to fine threading, heavier construction, black enamel/Japoning finish, and knurled top edge. There is a raised portion on the interior center that is also finished with same black coating as the exterior possibly to accommodate a gasket. The word SUN is stamped once on the top of the object. Anyone have any information?
