Query: /w/ for /r/ in any British dialects?

[Cohen, Gerald Leonard]

Are there any British dialects where /w/ can be substituted for /r/, such as "gwand" for "grand" and "dweadful" for "dreadful"? This feature turned up in the speech of at least some 19th century (U.S.) "dudes", who somehow took it to be refined British speech.  Was it based on anything actually spoken in Britain?
