I've got a few OTA wagons, both Bachmann and Hornby, and want to understand the timeframe for operating each livery/version. Included are some of the Hornby version pictured above as widely listed as being in 'Thames Board Green' livery (teal to my eyes).
Having done some research however I'm struggling to find any photgraphic evidence of OTA wagons in such a colour. From what I can make out the 'Thames Board' livery was light blue and didn't included the painting of the sole bar and suspension. Some OTAs were painted, including underframe, in plain green for Shotton traffic but this appears to be a very different colour than the Hornby version. Strangely the Hornby wagons in this teal livery also have post 1998 OLE warning flashes.
I've trawled through what books I have, Flickr and Paul Bartlett's excellent website but cannot find an early picture in this vibrant Hornby teal livery. Tom Smith's Volume 2 book has some pictures of OTAs from 2002 described at "faded green Thames Board livery" and that is the closest I've got but I cannot help wondering if they are faded 'Shotton' green instead.
Has anyone got, or can point me to, an ideally ex-works photograph of an OTA in this Hornby teal livery please?
