Not much you can do about the ear that's warped outwards, I suppose you could remove the hjandguard and bind the outward bend INwards for a year. But it WILL reassert itself - eventually! I would just make off the outer edge to suit

Cracked fore-end indicates to me badly fitted/fitting or knackered draws. Fix them and then open out the crack, drill small hole at the end of crack to relieve the stress, insert wood glue into crack and cramp. Hardwood dowel into the hole you droilled to stress relieve. I would follow it up with a hardwood dowel across the crack but then, I'm an Armourer and not an originality buff.....

All this has been aired several times before as I seem to recall
