JohnK I would say that action is a bit too significant to sporterize, being the first year of Edward VII's reign and all that, first full year anyway.

You can see it took a heck of beating when the barrel was removed: look at the peening over of the barrel ring and the lug the front guard screw threads into.

You call of course, but if you want charger loading and a two stage trigger a later action would be easier to use.
