An all original Dunhill E17 'prince' pipe from 1925.
Marked:
Dunhill London , "Inner tube" , Pat No 5861/12 5 (with underscore.)
The original innertube with Pat No and the stem with the original Reg. No.
The bowl is very much as it was 95 years ago on the out and inside. This pipe has not been used but very often in the past century.
For me it was a very nice 'ebay find' last year... Very bad pictures and only one more bidder starting at 125, euro.
Upon receipt I have only cleaned it on the outside with ethanol 98% and later with some Dunhill pipebowl polish and a little bit of Dunhill mouthpiece polish.
A few weeks later I gave it a double carnaubawax layer to make sure that I can use it when & where I want, like I do now.
