Antique Pewter Candleholders

Pair of antique pewter candle holders.  They are about 9 1/2" tall.  They have three levels or bowls, with the bottom being the largest(about 6" diameter).  The center bowl is 3 1/2" diameter and the top bowl is 2 7/8" diameter.  There is a spike in the top bowl and this top bowl is about 1 1/4" deep to catch the drippings.  There is a handle that is attached to the top and middle bowls.  At the top of the handle there is a ball on a stalk that was most likely to hold a snuffer.  I do not have any snuffers with these, just the two candle holders.  They are marked on the bottom with an impressed mark of an oval that has what looks like a crown on top of it.  Inside the oval there is a castle with a flag flying on the top.  On either side of the flag there are the letters "F" and "B".  That is about all I know about them except that they need some straightening since the soft pewter is somewhat bendable, but I'm sure they can be bent back into shape.  Other than that, they could use some cleaning which I have left undone.

Thank you very much for any help you can offer.
