I don't see any maker's ID on this saddle. It has been suggested that it is from the 1940's. Under the leather the horn is brass. There is a small circular geometric dot pattern stamp at the top center of the basketweave tooling on the sides of the seat. Anyone have a clue?
Found this image while looking for the stamp of a Simco Daisy. In the early days of Simco, they stamped the horn with a 5 or 6 petaled daisy. They were well known for their basket weave design. I would be fairly certain that your saddle is a Simco.
