Yeah, W. & C. Scott is supposed to have built the Hollands prior to 1893. They sold a lot of "Seven-Patent Scotts" with the Holland name on them. The "Dominions" sure look like Scott back-locks, especially the later ones (the lock-plate shape changed in the early '20s - the dipped edge became much less angular). I've always assumed that they came from Scott (Webley & Scott after '97).
