Xf-6

[R Austin]

There is also another six out there that has no numbers for a serial....... simply stamped "GENE EAST"......

These are pictures of the first 6 cylinder looper built in the spring of 1966 for John McMullen of Flint Mi. ( M-14 ).

The top of the block with Genes handy work and the side of the block where the serial number is normally located, you can make out "GENE" punched in with what looks like a very small pin punch.
