I found this relative new article (2016) about Trumper and the late royal hairdresser Mr Crisp and I don't think I have seen it been posted on here. It's about an auction of some old shaving related memorabilia used by the royal hairdresser, who described in the article, visited Buckingham Palace every two weeks to "trim the hair and beard of His Majesty George the Sixth. Following the king’s death, Queen Elizabeth continued to use the services of Mr. Crisp to cut the hair of Princes Charles, Andrew and Edward until Mr. Crisp’s retirement in 1971".
He was apparently employed at Trumper for 42 years. The article is well worth a read and the pictures including in it are wonderful!
Look at those gorgeous bottles on display!
