Royal Swan China : Help With Pattern

I have recently been fortunate to come into possession of a large Royal Swan dinner service. The only problem after searching Internet, eBay, Etsy and Replacements, I am unable to determine the pattern itself of the dinner service. I know that it is quite old which may explain why I have been unsuccessful to date. Any help or directions to where I might find the answer would be greatly appreciated.

 

You may find it listed under one of these companies, or not: http://www.thepotteries.org/allpotters/138.htm

 

Originally Booths, Then Booth and Colcloughs LTD.
In 1955 became Ridgeway pottery. Royal Swan is one of the stamps used by Ridgeway

 

Thanks for the information. Still having problems to find the pattern, although if Rudgeway is still operating, may try and contact them direct for assistance.

 

Ridgway, not Ridgeway.
Very few Royal Swan patterns actually have a name.
Probably 1950s/60s and unfortunately doesn't have much value.
I found once reference that lists Royal Swan as 1950-1974, don't know if that's true.

 

I don't suppose the partly obliterated stamp on the back means anything useful for the query? I can't read it but seems to be
_R__AND
226

 

I think it's ENGLAND 226.

 

Okay, thought I saw an R in there but can see that it could also be an N.

 

Thanks to everyone for their replies. I checked the back of several saucers, plates etc. and they all have different numbers on the back, so do not think that is any indication of the pattern.
