Peter is planning to paint a copy of a photograph taken 'many years ago' at Farringdon station.
As seen below, the photograph includes a T Stock train - wooden most likely, so therefore one of the earliest batches.
He is wondering what livery to paint it. Met Railway varnished teak? London Transport brown? red?
I have shown him a photo of the red liveried T stock sleet locomotive that I saw at the 1983 Acton Depot open day. But this is a metal bodied train and its livery might not be correct for the wooden bodied fleet - on this neither of us is sure.
