Yes,, common mods to the 1914/1917 rifles. Trouble is nobody wants to pay for them, anymore! And, when you're done, you will still have a a cock on closing, over weight rifle built on an 'antique' action. If you can get McGowen to do this for $500 you'd better jump on it. There are much better options, for your desired .458 Lott, to be had.
