I am lead to believe that Ben Wades of the Preben Holm era were not made by him but the factory was his at that time. I agree with Chasing on this. Preben Holm pipes, like the Delight, for example, I don't believe they were made by him either. If any of them were made by Preben Holm, I would imagine it difficult to tell which were carved by him and which were carved by another pipe maker in his factory. I was told by a high grade Preben Holm collector that the only pipes Preben Holm, without a doubt did carve, are the Preben Holm Private Collection pipes. Take this with a grain of salt because I am no expert. There's some food for thought though.
