I only thought of this option (3) today and that is to utilise some good 1907 grips currently, but incorrectly, fitted to a M1917 bayonet. I have been intending to either find some correct grips or make some with the double slots in the centre for this M1917 bayonet in any case. So it may be better to use what's on the M1917 on my 1907 bayonet and make or source the replacements for the M1917 because that needs them anyway. The 1907 would have good but Patinated grips.

Here are some pictures of the M1917 grips.

Any constructive thoughts appreciated, please.
