Vase Marked

When identifying old vases, what is the difference between Prussia RS and Prussia B ?

I have a vintage pitcher/tankard marked hand=painted in Prussia with an official seal on it. The letter marked on it is "B"
Why is this different from RS, and is one more valuable than the other?

I think the "B" indicates china made by Beyer and Bock and the "RS" to that made by Reinhold Schlegelmilch.

This isn't really my field but "RS" porcelain, particularly the pre-1910 stuff appears to be fetching higher prices that the "B"
