identifying piston in hemi

I have a blown hemi -Brad block and am trying to find out who the piston manufacturer is for the pistons I have in the motor, Bought motor so did not buy them originally. the numbers on the pistons are 447 AB-V3 + 001 with a 19432 and also a 472015. Looking to find out more info on them so I can get some spares, Yes I know a I can send one in to a manufacturer and get them scanned. But really do not want the motor down that long. Would rather talk to the guys that built them, Thanks
