The lid is brass & metal & white porcelain. The metal is rusting but it remains sturdy and intact. The base of the lid is porcelain (picture 6,7,8) The brass fuel reservoir has a key and key holder, not sure what for (picture 6) I'm not sure if all parts are present. What you see is what you get. My research shows the Maker's logo and date would be on the base of the reservoir, but alas, worn off.
My Research shows a date of 1941 WW2 era. Marked Made in England (picture 9) The overall height is 14" and it is 10" across at the widest part of the hood. A very unique and rare item for your collection.My listings are mostly all used, vintage or antique condition. I price according to the Whole lot.
