Buffers Query
Can anyone advise me as to the correct buffers used on British Rail Southern Region (so including stations like Waterloo, London Bridge, Victoria, East Croydon, etc) late 70s and early 80s?
I'm partial to the Accurascale Rawie Friction Buffers, as pictured, but not sure if they were introduced after this era?
Any photo references would be appreciated too. TIA.
