Superb Dave! Thanks for posting these additional Serials.

At the very beginning of IWM Film A70 135-3 we can see:

1. A truck with Serial '1318d' ('d' meaning "with diagonal bar from top left to right bottom"):
A70 135-3 - 480 - 1944-08-25 - Laws - 00.00 - Br lorries - 020 - AoS 1318d.jpg

2. A lorry with Landing Stage component, Serial '1302d', vehicule number K33:
A70 135-3 - 480 - 1944-08-25 - Laws - 00.00 - Br lorries - 097 - AoS 1302d.jpg

This is a Canadian unit, viz the Census Number starting with 'CL':
A70 135-3 - 480 - 1944-08-25 - Laws - 00.00 - Br lorries - 130.jpg

3. Another Landing Stage component lorry (K18) of the same unit:
A70 135-3 - 480 - 1944-08-25 - Laws - 00.00 - Br lorries - 203.jpg

4. An FBE truck, Serial '1317d', meaning 106 Br Coy RASC:
A70 135-3 - 480 - 1944-08-25 - Laws - 00.25 - Br truck AoS 1317d = 106 Br Pl RASC - 14.jpg

Sadly, the sequence stops there

Close enough to, but not quite, '1303' (presumably with the same white bar and formation sign) for 86 Cdn Br Coy RCASC as you found
