Definitely none on the Epsom-Leatherhead section. Besides, Epsom and Leatherhead both had separate stations for the LSWR and LBSCR.
None of Havant, Fratton, Portsmouth & Southsea (obvs. Farlington, Hilsea and Bedhampton which did not have canopies) have them either.
I cannot speak for the Wimbledon-Tooting line, other than that Wimbledon
does appear to have the same design (

If this is true, then we have Clapham Junction, Wimbledon and Portsmouth Harbour. I'll leave it to the resident historians to suggest what else these stations may have in common!
