| Description | Correspondence between Cannon and the Trade Mark Protection Society, re: the 'Hercules' Trademark No. 224420. Cannon's application for the trademark was under dispute due to another trademark in the name of 'Hercules' being already registered by Exton & Co., Wiltshire. Also contains letters to Exton & Co. asking for their permission to use the name 'Hercules' on a gas fire, as their trademark was for engineering, architectural and building contrivance. |
