When PYE of Cambridge applied for a grant of arms from the College, they also applied for a variety of flags (burgee, guidon, standard, pennon, banner) and 12 badges. This is their logo - not one of their badges:



There were, at the time 12 different divisions, of the company and each division used its own badge on internal communications. PYE also had a fleet of vehicles and they used the badges with a fleet number to identify each one.

PYE is now a small part of the Phillips Plc group and as far as I know have reverted to the use of their logo and no longer use any heraldry.
