By all indications, Dick Hoyt did not contemplate a forward draw holster from his patent application when he filed it mid-1930s; it was for a shoulder holster that c/b worn there or on the belt as a crossdraw. Indeed examples of his forward draw don't appear in his literature or surviving holster until his third era that was his shift from SoCal to Washington state.
A full roundup of Hoyt's five eras and associated marks for each is in my book "Holstory -- Gunleather of the 20th Century -- the Second Edition" available at www.holstory.com.
