Hi FoMoCo1 and welcome to Outdoorking. I can suggest three approaches you might try.

1. Check this internet page:
http://www.arboristsite.com/chainsaw/183549.htm
The person who posted the answer seems sure it has an automatic oiler, and tells you where to find it on the saw.

2. Check out this Outdoorking thread:
https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=4368
It appears that Bruce, the Outdoorking site-owner, has the parts list, or had it half a dozen years ago. You might try sending him a Private Message (see MyStuff at the top of this page).

3. Try this internet selling site:
http://www.ioffer.com/i/wildcat-38cc-mcculloch-chain-saw-parts-list-1989-144711631
It appears that guy is prepared to photocopy the parts list and supply it - I don't know him so I can't recommend him, I just found him with a Google search
