As expected everything is std size and looks great.

The original oil pump, it looks as good as everything else and made good 15psi at hot idle, i have absolutely no reason to doubt it, and compared to the 30 others i have in the loft it looks new.
Will a good condition stock oil pump be enough for additional oiling like what is required for a McCulloch or OHV heads?

Thanks.

Well, McCulloch superchargers were popular back in the '30's and '40's so the original oil pumps worked then. Should work now.
