I can’t see Weihrauch investing in tooling for two different castings when one is ample, just with a teeny slot machined in it for the 75. I’ve got both and apart from the slot for the release catch they look identical. Typically over engineered so no issues in taking the load in either direction. I’d guess the cocking force is about the same, albeit in different directions, if anything the 75 might be higher.
