Hi Mick
if you want to see before you buy then contact Vince at
The Turners Workshop and arrange to visit. He's at Camperdown close to The John Lewis and Fenwick warehoses, not far from Gosforth Park.
A really helpful and knowledgeable guy and has the best selection of blanks I've seen.
You'll be very interested in seeing his vintage acetate tubes and Conway Stewart blanks, loads of pen kits and other stuff as well.
Axminster on the coast road hold a few but not enough to make a special trip.
