rmb, no reason to be surprised at action similarity. Almost without doubt, both sourced machined actions from Birmingham; maybe even barreled actions or complete guns in-the-white. The smaller makers seem to have made good use of the trade. For now, we can only guess at how much work was done in the shop of/by Mr. Harkom his very self. However, we can for sure appreciate the end product, how ever he got it done, that Mr. Harkom got out.
