This patent specification has been disbound from a volume of 100 different patents. This is an original HMSO published item at the time, not a modern copy as are being sold elsewhere. The drawings are often ideal for framing. It is part of a collection of several volumes from the 1920/50's that I have from which individual patents will be sold over the next few months.

Thanks for the link, Rob.
I recommend anyone into old Aircraft, Railways, Buses, Cars, General Automotive Engineering, etc. to have a look at his very long lists of items for sale. There's some fascinating stuff on there, apart from numerous patent details, and prices seem reasonable.
