An extremely unusual Derby tea cup and saucer hand painted on Famille Rose style to replace damaged pieces of a Chinese service (original Chinese cup with chips to the rim is included in the sale).  Ex J. A. Robinson Collection.
The porcelain is extremely white.  It would be difficult to recognise it for Derby porcelain if it did not carry the factory marks.  
Rare handle.  Impressed "B" to Derby cup.  No gilder's numbers.  Derby cup and saucer in excellent condition.  Chinese cup with one chip and small fleabite chip at the rim.
