Vintage Flagg Bros (Brothers) Men's Loafers/Shoes w/ Tassels-Leather-1970s -8M?

These are gorgeous with black patent, and black suede uppers (They are really a lot darker than the photos).  These shoes are in very good condition with just a couple of VERY minor scuffs.  I am guessing that they are a men's size 8M, as this is the size my father always wore.  However, there are many numbers on the inside, none of which appear to be a size (this is normal for this brand of shoe).  The outer sole measures 11.25" from the outside tip of the toe to the outside heel.  The inside sole measures 11" from the inside tip of the toe to the inside heel.  Please know your size, as these are a vintage item and not possible to return or exchange.  I also have another pair listed exactly like this, but in olive green.
