I am going to guess it will be cut 2/16ths past center and the strike plate will bring it to 1/16 past center b/c I think thats how my Howatt Venturas are setup.
With regard to serial number, since the bow has AMO written on it, I believe it must be post 1968.
If its an older bow and serial is # is 224391 then I think the first number (ie the 2) indicates 1972 or 1982. If the accent stripe (red stripe) running thru the riser runs runs straight, then I think its a 1982. If the accent stripe running thru the riser runs in a curved fashion, then I think its 1972.
