According to the article The Rolling Centenary Collection by Pulfer & Williams in Special Interest Autos #78 December 1983:
The use of radiator mascots to adorn automobiles and add an individual and distinctive touch began with the introduction of the modern style radiator with its separate shell around 1901, and by the 1920s, many motor car manufacturers were adding their own unique touch to their product with approved mascots.
When I purchased my 1928 Lasalle Five Passenger Coupe wreck there was a rad and rad shell but the mascot figure of LaSalle had been broken off. At that time it was not a concern as there were too many other restoration problems to solve.
At the annual Red Deer Swap Meet held in May, 2013, I lucked upon an authentic La Salle (1927-30) mascot reproduction from the Rolling Centenary Collection (1983-84). The enclosed photo of this mascot reproduction shows that most of its advertised fine silver covering handcrafted bronzolite has been lost. Beside the mascot in the same photo is the actual pot metal mascot base with the La Salle figure broken off. This base shows the axe, the broken paddle, fire and shoe imprint. In the other photo is the underside of this base showing the approved production copyright for the original mascot.
The reproduction mascot presently on my restored Lasalle car has lost most of its silver covering on bronze. One day I will have to get it chromed. The other photo shows some kind of security contraption which was attached to the base of the mascot and rad cap found on my Lasalle wreck. At one time I had those pieces chromed and added the heavy wire which I can manipulate when attaching or removing the mascot rad cap. It is a feeble attempt to slow down the possible theft of my expensive La Salle radiator mascot.
