During the holidays I corresponded with some of our members across the pond regarding W. & C. Scott & Son and while none were able to help with these specific locks, amazingly, one of them had a personal copy of the Crawford & Whatley book. He was nice enough to look through it but unfortunately his report back was that there was next to nothing in it on the percussion era Scott doubles. So I believe I'll start a new thread with just the pictures of the locks with the hope that someone might have a Scott double from this period (1860's through 1875) who could compare theirs with mine.
