And here's another, from the other end, in the RCTS Archive.
Interesting to see it on a branch. Most of the slip workings that I have seen in timetables just served the one station. The photo shows it in traffic after its use as a slip.
Edit: And here's another, also taken at Bodmin, with the locomotive not blocking the view: https://www.google.co.uk/search?q=hawksworth+slip+coaches&tbm=isch&imgil=ZI4xBEa3_mfsWM%253A%253Bw2k5X9-rEeo1dM%253Bhttps%25253A%25252F%25252Fwww.rcts.org.uk%25252Ffeatures%25252Farchive%25252Fsearch.htm%25253Fcompany%2525253DGWR%25252526subtype%2525253D3%25252526class%2525253D%25252526location%2525253D%25252526srch%2525253D%25252526page%2525253D2&source=iu&pf=m&fir=ZI4xBEa3_mfsWM%253A%252Cw2k5X9-rEeo1dM%252C_&uFI6aet-3RdYigCesAy0bWKg%3D&biw=1366&bih=633&ved=0ahUKEwiro9GCqdHTAhXJCMAKHb3hCrEQyjcINA&ei=TYoIWevIG8mRgAa9w6uICw#imgrc=W8MolmzRqzi1vM:
And re-edit: Since both photos are labelled as being at Bodmin (I have a slight doubt about the first one), I assume that they were taken on the same date in 1963. But the second photo looks to me like carmine and milk, rather than chocolate and cream. Does anyone know what the paint scheme was? Would they have been on trains that had Chocolate and cream rather than crimson?
