Nice rifle. I feel the Westley 1897 is the best mechanical design of all the British falling block rifles. It has a rebounding hammer and inline rebounding firing pin with a small diameter tip. Much better for high pressure rounds than other makers concepts. I do like a top tang safety though, especially the design used by Wesley Richards. Much more positive than that used on PD Farquharsons and not dependent upon the action screw timing. Enjoy your new rifle in good health.
