Appeal for help! 

I have been searching books and the internet trying to find a definitive reference for British Tank Markings in the mid 1980's specifically 1986. 

Thus far I have got OSPREY ELITE 026 - TANK WAR - Central Front NATO vs WARPAC

It's a Great book, and I can recommend this to any Cold War Era Wargamer, most of it is Black and White but the central 12 pages have colour prints of Vehicles in various Camouflage and colour schemes.

ARMOURED ACORN Website http://www.armouredacorn.com/as reference Sites.

I would like to know the Squadron and Platoon marking systems for the Royal Tank Regiment at this time. It's essential so I can use the TL-MODELBAU Decals I've got effectively on the British Vehicles and finish them properly. 

Any help would be appreciated!!!
