military bridging

[David Potter]

Can anyone help indentifying following:

1. What number was carried by 128 Bridge Company RASC (operated in support of 30 Corps, also known as Boar Bridge Column - presumably in reference to 30 Corps symbol)?
I suspect 1317 or 1318 on RASC Green/Red square with GHQ reverse diagonal bar.

2. Indentity for 1205 on RE Blue square with Army Troops bar at bottom?
I suspect could be linked to 7 Army Troops Engineers.

Maybe some bridging vehicle enthusiasts have this information; otherwise I shall start a new thread to indentify obscure unit serial numbers - the Canadians units are relatively easy as they were the best documented forces!
