It occurred to me that maybe the edges of the holes were deformed from using other fastening approaches. A small screwdriver sliding along the bor towards the out side of the hold confirmed the deformation. A tapered reamer was used to lightly dress the outside edges of the hole.
The bolt slipped right in.
This is what was used to clamp the post upon arrival

Using a standard 6mm socket binder bolt, likely not the original configuration as there is a key notch on one side, Patina and all. I have come to appreciate the history the chips and overall condition of the paint.
