Es un tema muy interesante y por lo que estuve observando, cada fuerza tuvo su clasificacion, seguramente en algun momento de la guerra ó despues las unificaron.
Los norteamericanos en la WWII utilizaron un disco pintado de amarillo ó un circulo amarillo pintado en el parabrisas.
Tenia que ser algo visible, ya que los que custodiaban un puente, debian identificar rapidamente al vehiculo que se preparaba a cruzar y detenerlo si sobrepasaba el limite del puente.
Estoy buscando la clasificacion, pero en el caso de los jeep , encontramos el numero 2
y si llevaba trailer 2/2
Estos son los datos correspondientes a las Fuerzas Canadienses
Bridge Classifications
Bridge signs were usually a 9" yellow disc with black numbering. Sometimes a black disc was used with the number outlined in yellow. The correct shade of yellow is 356 (previously No56) Golden Yellow from BS381-C.
Examples of signs, the first has a weight classification of 5 tons the second is for a towing vehicle of 18 tons with a combined load of 50 tons.
As with all Army regulations, rules were not always followed and lists were often revised.
The following list was published in 1943.

Aqui un Carrier
Posteriormente( y no se a partir de cuando) comenzamos a ver la Bridge Plate con numeros intercambiables
La letra C indica que remolca un trailer
Los vehiculos de la AACVM adoptaron informalmente esta ultima brigge plate , para informar el numero de socio al cual pertenece el vehiculo.
