I have a coffee set with a mark that I believe is Retsch. I would like to know the pattern number/name, if possible, and any information known about when it may have been produced. I have tried contacting the company that bought Retsch, but they say they have no records of anything produced before they bought the company.
Pretty sure that is a factory pattern number but you should check to see that it corresponds to your pattern !! They are usually pretty dependable but its like everything else where people enter the info !! Errors are possible !!
Then the first pattern on that page is yours,, Pattern Number 6637 !!
