Just for the sake of illustrating Webley & Scott's dominance in the English gun trade I've often estimated that 75% or more of the guns made in England had some W&S origin. And yes, that would include a number of the lesser well known London "makers" I also suspect that a high percentage of their "unlabeled" guns were totally finished in house. They had the ability to totally make a gun, whether it was rough forging actions and furniture or boring and finishing barrels. Few, if any, of the smaller makers had the financial ability or volume to make an entire gun from scratch.
