No idea if these dates are 100% accurate, but pretty sure they're close enough. 

I thought the strike was 91 myself. 

The local logos (Penshaw Monument in the case of Wear buses) were placed by the door if I remember correctly. 
Gateshead had the torch, Shields had Marsden Rock etc. Can't remember the other depots such as Chester or Percy Main unfortunately.
