The Ford 172 engine was fitted in the H 30-60 H series.
The continental G193 was fitted to the H30-60 F series

They were very similar trucks and probably the best way to differentiate between the "F" and the "H" is by the steering axle.
The "F" steering axle had a quadrant between the upper and lower steel axle plates. The power assist was from a hyd. cylinder that was mounted between the frame and the quadrant.

The "H" had a steering cylinder mounted crossways between the upper and lower parts of the axle (not a welded fabrication as on the "F")

Serial numbers
H30-60F started with B3 or B003
H30-60H started with D3 (or D003) OR later with E3 (or E003).
There were no C3 (or C003) serial numbers.

D3 had the Ford engine
E3 had the GM 4-181 engine

The only forklift truck that I know of that had a Ford 172 engine was a Hyster H30, 40 or 50F. The 30, 40 and 50 represented the capacity. For example an H50F would have a capacity of 5000#.

If you really want to fix up this "cool" lift truck that you know very little about, you will need to at least know the make, model & serial number - many s/n are stamped on the frame some where - location varies even with the same brand. If the unit has been repainted more than once you will have to do some close looking & paint scrapping. Good luck.
PS: Owning and restoring an old lift truck would be a worse investment than owning a boat. Many people say a boat is nothing more than a hole in the water that you pour money into. But some "chicks" like boat owners with cool boats - don't know many that like "cool" lift truck owners and I spent 41 years around lift trucks. In 1982 I came up with a bumper sticker for a company called KD Manitou it read "KD Manitou We Can Get It Up For You!" and we got a lot of interest in them (bumper stickers that is) at the Permian Basin Oil Show in Odessa Texas - 20K to 50K show visitors
