I noticed a couple of these guns showing up on the auction sites. They seem to show up in batches. H&R made these extra large frame revolvers from the earliest American Double Action productions in 1883 or 84 and up to around 1920 or so. They are the largest bore revolvers/handguns ever made by H&R for commercial sales. They could handle either the British .44 Webley or the slightly smaller American .44 Bulldog, both of which are black powder center fire rounds and are no longer commercially made. I have examples of the cartridges, but God only knows where they are at present. Anyway, here's a couple old timers that surely must have some fine stories associated with them, considering the "honest" wear and tear they exhibit.
