Comment The holy lamb is a reference to the patron saint of Preston, St Wilfrid, as is 'PP' - 'Princeps Pacis', which means 'Prince of Peace'. Note that the operator of Preston Corporation's horse tramways (W Harding and Co Ltd) never issued uniforms (see link), so marked horse tramway buttons almost certainly never existed.
Given that the name of the undertaking was changed to 'Preston Corporation Transport' in 1931, it is highly likely that tramcar crews would have been issued with new uniforms bearing 'Preston Corporation Transport' buttons before the demise of the system.
