I believe you have that backwards.
You rotate the housing WITH the rotational direction to retard the timing, against the rotation to advance it. So, given that the Mallory has mounting "slots", you'd rotate the housing in a clockwise manner to advance the timing.
On a crab distributor you loosen the points-plate screw (right side of distributor) and push the plate down/clockwise for increased advance. This causes the points to open sooner - creating advance.
On a SBC, the distributor rotates clockwise, so you rotate the housing counter-clockwise for advance.
Hope this helps.
