Do these marks on the caps mean anything interesting?

Hi all, i was just curious if these marks were of any significance? Does anyone know what they are?

I've always felt that such well intended marks should be non-invasive; in other words, I hope the cap hasn't become distorted by them.

Holdenpaedia, they're the brakes Mate.

What they are is a numbering system for the rods and caps so that the right cap goes with the right rod, oriented correctly, and in turn they go to the correct position on the crankshaft. Bit of a bodge way of doing it as that cap etc, receives 6 hits with a hammer and punch, whereby using the number punches would be hit once.

At least with a centre punch, if it is sharp you only need to hit it fairly lightly because the force is concentrated in a tiny area. A number punch has a much larger area touching metal to metal so you would need to whack it quite a bit harder for the same depth of indentation.

What you say is right if using a larger type of number punch, but by using a smaller punch, it would not require that whack but a softer hit.

A centre punch will cause far less possible distortion of the metal and require a far lighter hit than any number/ letter punch regardless of the size (unless they a near microscopic). But personally I would use paint pen (if not being cleaned extensivly etc) or a scratch mark/ engraver mark before grabbing the hammer. Actually I have just kept the order correct during rebuild even if you have to tape them to card board in sequence with the push rods so with that in mind I guess I would do neither.
