Hi Conrad, the four finger grid grounding may be there for the purpose of  
neutralizing the plate to cathode feedback path.
Sort of like you may have seen individual fingers removed from fingerstock  
to create a small inductance from grid to ground.
I have seen many 8877 2m amplifiers that use this technique.

I have a  grounded grid 3CX800 2m amplifier that needs some TLC. One of the 
most  alarming things is that the grid is grounded by 4 small pieces of 
fingerstock  that has seen better days.  I thought that I would remedy the 
situation  and so I am looking for a grid collet or the SK1900 assembly. I have 
just  moved to the Netherlands and as yet have not learned where I can buy 
suitable  fingerstock that can be formed into a rig. 

Any help would be  appreciated.
