I know theres not much left of this but wondered if anyone can identify it and if possible show a complete example.
Approx 4.75cm x 4.25cm
Thanks

Guess (educated) - No. 4. Mk I Adapter for use with something like a No. 2 gaine. It would appear that the threads have stripped and the diameter, if they were still present would be 2".
