Based on all the input I've received here, if I do decide to strip and re-do, here's an enhancement I did on a Lancaster a while ago that might be about right for this old Lefever:

That is quite nicely done, Mark. Looks well-suited to that buttstock. That bottom photo seems to make that stock look very deep at the butt.

Thank you John. It was indeed deep at the butt. I've noticed that english guns seem particularly well suited to enhancement for some reason.
Wonko, that Creative Arts bulino is amazing. I've seen their work before. I did a Beretta fantasty trap stock that was along those same lines recently . It's fun using those kinds of juxtapositions.
