Been doing some searching mate.all I see is 2a with the dished pulley? Vintage mower site said the dished 2 part pulley was unique to the 2a ,and only a handful were put on mod 3.The flat top pulleys are unfortunately a dime a dozen so to speak.But the top hat pulley and especially the dished pulley are worth considerably more.i see a person on eBay selling a dished pulley for a 2 A for a whopping $300. Hope someone else can add to this topic
