2 Pounder Buffer Screw
 

Anyone out there able to show me the 'missing' part of this screw?
after sandblasting the barrel/breech block I found the buffer securing screw had been sheared off.
The 'ezi-out' worked, now to see / have dimensions of the counter sunk? head.
Thanks in advance.

That's not a buffer like a 25 pr, it's the breech closing spring case. The screw is a slot head countersunk to match the profile of the hole in the spring case.

I'll get a picture later.

Overall length is 38mm
Head diameter is 16mm
Countersink looks like 60 degree.

Thanks Tankbarrel, yes - Case, Spring, FL 43 A.
I was lead astray by a local 25 Pdr Gent.
I find that a 16mm csk head, leaves the screw head proud of the locating hole.
What does the screw look like when in correct situ ?

Looks like this Graeme:

Flush as hoped, simple, thanks for that.
I'm finding restoring this GMH South Australian piece very entertaining, from finding and buying a full set of BSF taps & dies, to decoding the mysteries of taper pins.
The machining and castings are amazing. I have more questions relating to other missing parts, ..... back soon.

I finished a total rebuild of mine last year so happy to help.

Tankbarrel Congratulations, the set up looks amazing, and I'm aiming for the 'same' colour as yours ( not green ), could you show the original condition of the 2 Pdr before restoration ? ......... then I'll show you mine
