I had both a 28 and 12 bore back action sidelock marked Cogswell and Harrison, and an H&H Climax model 12 bore that I sold to Cabela's a couple of years ago, all made by W&C Scott of Birmingham, apparently. On all 3 the barrels dropped and pulled rods forward to cock the locks. I sold that 28 bore to Don Shrum 20 years ago and wish I still had it, it was a wand. Too bad you can't keep them all.
