IM-IV page 15 documents Count1Types and Count1Resource, which do what you 
seem to want.

My question is, what do you really want? Do you wish a new file that contains
the same resources as the old file? Do you want a file that is byte for byte
identical to the old file? How about the creator and file type? Finder Info?
Creation and modification date? If you copy a locked file, should the copy
be locked?

I have a routine I wrote a few years ago that handles all of these (I think)
If there is an interest, I can post it.
