Newt: 4. Brown (see 0:09 + 0:11 + BL), 14. Unknown (see 0:15), 10. Geelan (BL).
There were a few late replacements for Newtown like Ray Downie normally a forward playing on the wing, Geelan moved from 2Row to centre, Brown from entre to HB & Ellis from reserves.
PP: 16. unknown - could it be Price who was a late replacement for Fenton? (see 0:12)

To me #14 looks like Michael Speechley I don't see #3 also saw #16 for Newtown looks like Ellis and looks like Downie in #5
#16 for Penrith is Robert Jackson.
