I did think it should have been V111C , as they were the model used by Allen and Simmonds. Should you ever need one I have a new piston (cast iron) for one of those , along with a used , but good cylinder barrel.
I would go along with your views and measurements , but as you say , we’re not dealing with formula one engines.
Many years ago I fully rebuilt a 25A on an AutoCulto model L , the crank rebuild cost a small fotune back then , I dread to think what the cost would be today.
