X.3652. RE SYLPHON TUBING.

In accordance with Mr. Royce's wishes, would you kindly enquire whether the metal spinners and pressers in Birmingham can produce a sylphon tube from a plain tube made by a cartridfe like process.

We send you herewith a model of 2.375 diameter sylphon tube. On the sketch below we give the demiensions of the actual sylphon tube that we propose to fit on the 40/50 H.P. chassis, which we want the Birmingham people to make if possible.
