1938 G14 whereabouts

[Y13 Alan G]

On behalf of Linda Pargeter I am trying to find the current owner of her late husbands 1938 BSA G14 Reg "GMP 493". The bike was sold at auction some years ago and is unusual for a 1938 G14 in that it has handchange gearbox. Vincent Pargeter had the bike fully restored before it was sold. Linda would very much like to know where the bike is and if it is being used.
Linda & Vincent Pargeter over a period of 18 years fully restored the Norfolk Wherry "Maud" which is in regular use mainly for tourists. The wherry is now owned by a Trust.
Any help appreciated.
