I've got one. You are right Pemps did order about 30 I think but Neil Dowson from the club took the order over and I had to collect it from the club. It's a great top, but would have been better in short sleeve, but then it would not be a replica. Anyway no way would I sell it. I wore it at Wembley and the number of people asking me to sell it was remarkable.
I'm sure the club shop could sell at least 100 if they had some more done.
