Hi Brad
Welcome to the Canadian section of the forum.
The blunt "G" is on the right.

No idea where I copied this from, so can't give the appropriate credit.
Not sure what you mean by "how are the sheet position numbers on the sheet laid out.", unless you mean "what is the position number(s) of any "blunt G" stamps on the pane". If so, I don't know the answer, but perhaps someone else has plated this issue and will respond.
