So, now that I have had time to think about this, a Martini action it is. Almost certainly 577/.450 cal as it is unlikely to have been .303. They were Lee Enfields in the main.
I have taken some more pictures and first off, it is definitely .22 cal, the loading tap measures out at a little over as you can see in this picture below and the picture below that:
These next pictures, apart from showing the beautiful brown patina, also show how the action has been modified. It is clear, now that I have looked at pictures and diagrams of the Martini actions, that the CO2 cylinder attaches where the barrel would have been and the barrel and new breech block are on the top:
I have seen something like this and it was by Leslie Westley, it was a single barrel shotgun (I have a pic somewhere but it is from back in the day when we used Instamatic cameras and sent the films off at the Chemist!) I will dig it out and get the scanner out.
This is the barrel business end and it is a full tapered barrel, purpose built for the job:
Here is a view from the "underneath" with the for-end clipped off, nicely done and you can see how the barrel has been machined to accommodate the CO2 cylinder:
And yes, it is one of my collection. Only the weird and wonderful here

An Emergency on your part doesn't necessarily mean an Emergency on my part!
