In an antique and collectibles mall today I found another Bernard Rooke Pottery vase!
However, while there's a label on the bottom saying "Bernard Rooke Pottery The Mill Gallery Swilland Ipswich Suffolk Tel. Witnesham 460" the initials which I think I can see (they're very faint) on one side look to me like FR not BR
So I've emailed Felix Rooke again to ask if it's possible that the vase is his work, rather than his father's.
I'll let you know. Watch this space .....
