Another Darne with a weird stock. One often sees these with very straight stocks. Mine has less than 2" of drop. Forget about trying to bend it down, no wait, it may be possible but will require removal of the thru bolt threaded in from the front of the stock, hole bored out and doweled, stock bent in a jig that you will have to build special for this stock, new thru bolt fitted (or possibly old one) and finally hope stock stays bent. The new Bruchet Darnes have a standard type thru bolt that's inserted from the butt but I'd expect they would be equally difficult to bend.
