I've just checked the 1936 trade price list, and it's there. It is reasonable to presume that the 1936 price list was issued in plenty of time for the Christmas 1935 market, around late summer/autumn 1935. It's listed as a "Bulb Bowl", was made in "Matt Black", and is listed both with and without the bulb support.
So, as it is not particularly common, the speculative post-war date in my first reply is probably incorrect.
