Early original brass dog bone radiator cap accessory. This has a spin away top for easy filling/checking water level. Could replace the top knob with mascot. Good shape for age. See pictures. Feel free to ask questions. No reserve.

Measures around 6-3/4 inches wide and around 1-3/4 inches inside diameter on threads.

I am just beginning to list a bunch of rare early automotive accessories from life long collection that started in the 1960’s. Keep an eye on my upcoming auctions. All listings with the green background are no reserve auction and start at $0.99.
