A lovely leather bound book. Don't know the exact date but believe it is between 1926 and 1934. This from references within the book.
It has 526 pages and is quite a weighty tome.
I'm familiar with most of the items offered in the catalogue but I have never heard of a tue iron.
Please see link to scanned page.
My best guess is that this is a nozzle to inject air into a furnace, forge or brazier.
I have tried my friend google but she is having an off day.
Many thanks, Nick.
