carving machines

[cricket]

Hi I am looking for information on Propeller Carving machines, I read in a old aircraft maintenance book that they used to use a machine for Roughing out the prop blanks, it was called a propeller lathe or profiling machine. I have 1 picture of such a machine manufactured by
J.Sagar & Co.Ltd.
Can anyone help me wih any further information/pics on these machines.
