There is an earlier thread in here that discusses/ debates the makeup of a master set. I think Ted Z and others posit a traditional number there that includes the catalog variations,including the grey back Canadians and the 3 DPs. But if you look at the CL for the Super Set in the H & S auction ( link in the beginning of the Campos thread, or google H&S 1952 super set), it lists several additional print defect /variants not in the traditional lists and totals 579. I do not think everyone would buy into all of them, but it would expand the list if followed. I am going to be out of town for awhile but when back plan to compare my list with the list for that super set to see if I have any not on that list. I know I lack some on that super list and have started looking for them :-/
