We can pretty sure claim the pipe as an unknown before and not registered in catalogues John Redman factory product. Courageous combination of the classical stummel and fancy stem, specific stamping (LONDON MADE under a brand name and MADE IN ENGLAND on the opposite side of the shank) plus the specific model of the metallic air cooler - everything that is very and very typical for the John Redman LTD & British Empire Pipe Co products. The pipe remains in our collection.
The pipe markings are "BRITISH KNIGHT \ LONDON MADE", "MADE IN ENGLAND". The length is 13.2 cm (5.2"), bowl's height is 4.7 cm (1.85"). External diameter of the bowl is 3.7 cm (1.46"), internal diameter is 1.9 cm (0.75"). The depth is 3.8 cm (1.5") and this pipe weights 38 gr. Briar, vulcanite stem, aluminium air cooler.
