Carry on if you're happy, but this thread is about books on FM Konstglas (I wasn't aware of the distinction between the two makes) and you'd maximise the input you receive by starting a new topic, specifically on Royal Sweden Crystal - there may be collectors of this glass, but not Konstglas.
Not much point in throwing all Konstglas/RSC/Ronneby queries into one topic or you'll end up with a 38-page topic like the Chance glass one... spread it out a bit!
