Older Doc' Ihave been asked if the 'Oil Tank' is an Original'Seems that there is a Repro on the market(Somewhere) Have you looked at the markings on the underside? I was told an 'Original'sold in London at One of the "BIG" Auctions, and is being used for the pattern for the'Repros' the 'New' ones dont have the correct markings on the base.(But for 'Brit' 125.00.pounds!!!!'WOT ME WORRY"!
