Hi all,
 thank you for your comments.

This tends to leave me a bit puzzled as to why the factory did it the way they did. All your observations make perfect sense.

The factory drawing of the rod is not clear enough to see the details I'd like to see, although it does show the chamfers:
   

The rods were as made in 1929 when I disassembled the engine for overhaul, the pic  showing the groove and the two 1/8" diameter holes which I can only think are there to shoot a jet of oil on to the bore of the cylinders :
   

Cheers,
Stephen
