Immediately after WW2, it looks like Milbro and Webley were in competition to buy (or maybe requisition) the machinery and plans from Meyer & Grammelspacher. Milbro ended up winning the bid, but judging by the fact that Webley's production right up to the 1970's leaned heavilly on pre-war Diana designs, and included at least one model in the line up (at any one time) that was a rebadged Milbro, I think Webley and Milbro must have come to some sort of "arrangement" that allowed Milbro to get the production machinery.
