Claycrusher1900,
The book, "W & C Scott, Gunmakers," by Crawford and Whatley is pretty much it. They put together DOM estimates by serial number based entirely on their own research, using known W & C catalogs, patented features, etc. They acknowledge helpful input from Geoffrey Boothroyd, as well.
So between he and them, i know of no more thorough research trove regarding Scott. Even so, the book is only 92 pages long.
I believe a separate book by another author has been done on Webley, but dont know how much it touches upon the pre-Webley years of W & C Scott, if at all.
I have the book and can look up your serial number if you wish.
