We could show you the latest developments in casting tech- nique—the amazing complexity of the designs now in production—the ever-closer dimensional accuracy of our “ near-finished” components. We could also tell you about the wide range of alloys available—the freedom from porosity and the searching tests and high standards demanded by war service conditions. The advance in technique now being achieved will eventually become available for post-war production. In this way castings of greater accu racy, high strength properties and minimum machining requirements will be offered to all industries as an economic possibility. oAs g o o d as g o o d s o u n d c a s t i n g s c a n p o ssib ly be THE BIRMINGHAM ALUMINIUM CASTING (1903) CO.

To us, Tweedledum and Tweedledee represent those engineers who think now exactly as they were taught to think when they were serving their time in the works. They say “ We’ve always made our own Die Sets and we always will.” They forget that times change and that it is now possible to obtain your Die Sets 44 bespoke or ready-made*’ from Desoutters. They forget that by allowing their tool makers to continue to make Die Sets as w ell as Press Tools they’re wasting valuable time and money. A Desoutter Die Set is bound to be at least as good as, and certainly cheaper than, any they can make themselves, because we are specialists, and have a standard range covering almost all requirements. A Desoutter Die Set will not shiver. You do not need skilled labour to change the tools. The Punch and Die w ill be accurately aligned because our Die Sets have precision made Pillars and Bushes. Now, Mr. Tweedledum, what about a Die Set for you ? Give us a ring and tell us: the size or type ; the amount of “ daylight ” ; the diameter and length of shank; and the stroke required. t It will cost you between £2 7s. 4d. and £42 Os. 6d. ; according to your requirements.
