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 1893-1900,1907 & 1920/50's that I have from which individual patents will be sold over the next few years.
