Communication unit markings

[Eric B]

Hello

Not about wireless equipment but looking for Communications Unit markings.

My 1967 M38A1 was 2nd Canadian Signals Squadron. Looking for the white number that would have gone on top of the Blue and white square. Also any vehicle photos of the same time period.

I beleive Jon Skagfeld indicated he was in this unit.

My 1974 M151A2 was 1st CDN Mobile Brigade Group Signals Squadron. Looking for vehicle markings that would have gone with the NATO black rectangle with the bolt of lightning inside it. Any vehicle photos would be appreciated as well.

Thanks

Eric
