thanks Glen once again you helped me out in record time , you certainly know Carnival glass, I think I may have to buy one or more of your books,I find its a good way of learning buying pieces if not too expensive and researching, can I ask you one other question as its my wife who has only just started collecting carnival glass, I only last week bought a pair of Northwood green ruffled Peacock bowls from Kempton Park very cheaply they have the Northwood mark in a circle on base approx which year would they have been made
