I'm after some clarification as to the livery applied to several OTA timber wagons in the 1980's.
I'm referring to the (exclusively??)ex OCA conversions that carried 'Thames Board' livery on round wood traffic from Scotland to Workington and various other locations on Speedlink services. My own photos of the 'Thames Board' livery adorning these OTA's is a dark-ish blue. Various books in my possession also show photos of these ex OCA OTA's in blue , but some are pictured finished in a pale green colour that is also described as 'Thames Board' livery, or 'faded Thames Board' livery. A mate of mine maintains that this green livery was connected with the Forestry Commission (or whatever they were called back then).
Did the 'Thames Board' livery change from blue to green, or was it simply the blue fading over time to this pale green colour?
Thanks for any help.
PS: I realise many ex VDA OTA's were finished in blue for 'Kronospan' traffic to Chirk and the unique ex VDA OTA (with big stantions) was finished in 'Forest Enterprise' green.
