8/29/19 - This is a Webley mark IV .455 conversion "kit" which is more like an insert for the .455 revolver to make it fire .22 LR. This .22 barrel slides into the existing .455 barrel and the cylinder is removed, allowing for single-fire .22 caliber long rifle bullets. WW1 era production and in great overall condition. See final "photo" for a link to a video showing how the conversion works. A very scarce item, and in great overall condition. Bore has nice rifling but some residue / wear, 8/10 overall.
