Jani:
If I'm not mistaken all the Andrew Jno.(Jho.) Hy. & Co. Ltd. Toledo Steel tubes have a Sheffield, England stamp. But they were made in Liege, & I would hold firmly with the same for Franz Drescher's wares.

I have serious reservations that any JNO. Hy. Andrew Toledo steel tubes were rolled in England.

J. Novotny did the same:
