This Bioscope was made by Charles Urban after he left the Warwick Trading company to found his own company. With a serial number of 1142, assuming that the starting number was 1001 would make this a very early 1900’s projector. I have in my possession a copy of a 1906 catalog in which this particular projector is illustrated. It is possible that they were made prior to 1906, but certainly this particular projector was made in 1906 or earlier.
