Though sometimes people find a number and it's not the serial number, but some other part number.

BTW - some sources have that in 1956, Sears was getting machines from White , Soryu, New Process Gear and other misc companies - but none of them have serial numbers that would have started with a FZ.

I hope that explains why without pictures, there isn't much help that can be provided.
