Crockett & Jones is a private company and, as far as I know, is still owned by the same family/families that founded the firm some 125 years ago. There is a connection between Turnbull & Asser and the Crockett & Jones shops (three by now) in London. At one time (although not in the latest catalogue) you were asked to make cheques (or checks) payable to Turnbull & Asser. I believe (but I don't know for certain) that T & A (a privately owned company) has a franchise for C & J shops. Maybe C & J had no interest and no expertise to venture into retail on their own. Unlike Church, which retails since the 1920s, retail doesn't seem to interest the big shoe manufacturers. Franchises are quite common these days, many stand-alone designer shops are actually not owned by the company itself, but by a franchise holder (who has provided the money, takes the risk, but also gets the profits).
