Not for an engine, so I don't care about either model or condition of
the bores, and I will likely cut the piston end off. It would be
nice if the beam section has two parallel faces. If the bore is a
bit smaller than 1.37 that's ok as long as there's enough that it
could be bored out.

Any likely candidates from a popular engine?

If you don't find any joy from this newsgroup, drop by an automotive
machine shop in your area and ask. For that matter, ask if they have any
junkers that they'd be willing to part with -- you may get one for free
or for pennies.

Keep in mind that the hole in the con rod is larger than the journal
bearing diameter -- I assume that you want a rod that you can clamp onto
something, with a 1.37 (not 1.370?) bore, without the bearing.

If you need the bearing, then things will get a lot harder.

Seems small for automotive but maybe jap.

Perhaps snowmobile, motorcycle, lawnmower ~a 32mm crankpin would probably
work.

According to my old books a '73 to '74 Renault r17 crankpin is 1.190
inhes, but I wouldn't bet the farm on it. Without the shell you'd be
in the ball-park.

Briggs V twin has a pin size of 1.314 but the cap is angled not 90
degrees to the beam.
