Which may explain why old Kaywoodie pipes are sought after by some pipe collectors. There is even an entire forum dedicated to Kaywoodie & Dr. Grabow pipes.White Spot/Dunhill pipes are most certainly factory pipes, made in many duplicates of the same shape and finish, and among the most expensive factory pipes. Whether they are suitable to their price, they are extremely handsome to me. I think the pricing is a marketing accomplishment.
The factory has been the training ground for many superlative artisan pipe carvers, including Les Wood, who made Ferndown pipes for many years. As I note from time to time, in the 1950's, Kaywoodie pipes were the primo pipe on the market in the U.S., and Dunhill's ran second. Neither was as expensive, relatively, as White Spots are today.
