Some time in November I passed an old roundabout red triangle sign (the type with the triangle on top used before 1963) at a dual carriageway in a bunch of signs on the central reservation. Being distracted I didn't note the location but going back on my tracks appeared to be opposite Tolworth Station on the Kingston Road. I went back a few weeks later and nothing was there, and doing a project to record every pre1963 sign I can find as they are fast disappearing, have learnt most London locations and visited the majority already.
