Crankshaft id???

OK - so - yes I've read all the posts on identification etc... pretty sure I have a regular old stock 1948 crank ( 59AB) but - is this bad boy maybe an early aftermarket replacement? no markings other than a 4 stamped on the first flyweight - no clean out hole on the first one - and the fat flyweight measures 5.5 across... anyone? Bueller? Bueller?

59 crank (actually 29A, I think) should have single oil hole in each rod throw for floater bearings and no cleanouts. Also no need for cleanouts! The oil passages are straight through from main to rod, and can be full cleaned out by putting a brush through the simple straight hole.
