Many thanks I've now fixed the finger using the pin punch set which is incredibly handy and essential for precise pin pushing work!

Finkal 7 Piece Short Series Punch Set
I/N: 5610081

I got this set at Bunnings for $39.98 - I used the smallest one first 1.5mm thru the smooth end to push out the knurled end - then I realigned the finger that was out.

Whoever was the peanut that did the fists wasn't paying attention - now I have a hole in the finger but it's not visible once fixed.
