This saw was sold on eBay two days ago. Unfortunately I did not win this bid - missed it by a notch. I am really angry at myself… I don’t know what I was thinking… Anyway, this post is after the BSSM release and we are all a bit more knowledgeable or at least have a book to learn from. From BSSM we can learn that there were three time frames that Moorman's firm operated within. The closest stamp example shown in the book would be one in the middle, dated ca. 1800, which suggests that the firm at that time is the Moorman & Sons. There is more information on this maker and company in the “Christopher Gabriel” by Jane and Mark Rees. Using this example, I would love to learn from Simon how he arrived with this estimated date. Explanation would be a great exercise for me and most likely to most of us.
