Symbols traded on the London Stock Exchange have the following suffix added to the end of the symbol = :LN
LSE Index symbols have the following prefix added to the front of the symbol = ^ They also have the following suffix added to the end of the symbol = :LN
LSE Equities utilize the common symbol with the suffix :LN at the end of the symbol.
The exchange assigns a three (3) letter code to Equities. If the symbol is less than 3 characters, they add the "." character to the end. eg. RR.:LN
The London Stock Exchange appends other characters to the end of the symbol for classes, preferreds and warrants - but not consistently. eg. a "W" ,br> at the end doesn't always mean warrant.
examples: RR.A, RR.B for Rolls-Royce class A and B.
NOTE (to be updated): The LSE also has a bunch of symbols that are two letters and 2 numbers, that are coded as equities or bonds. These may be miscoded as equities as they seem bond related, based on the name:
examples: 91PU:LN 91PR:LN 51YQ:LN
