OK, no hints, so here is what I did.
Cut out some 5-6 oz leather, and skived the edges to make it lay flat. Measured a 4" wide piece and then snipped it here and there until it was what it needed to look like-used a Bear Cub with a good grip as a model.
Got the the leather wet, then molded it to the bow. Then I put some Tru-Oil on the bow and three coats on the handle where there really wasn't much if any of the original finish left. Let them both dry well. I then used some leather dressing with a a bit of brown dye to darken the handle a bit so it didn't look so new.
I used Barge Cement to attach the leather. a light coat on both the bow and the leather. Let it dry some and used it as a "contact cement". Put light pencil marks on the bow after test-fitting the leather to keep the cement off everything not covered. After applying the leather, I used some more Barge's to glue down the "flap" to finish it up.
And here is what it looked like when it was done. Added a thin pigskin leather shelf and strike plate.
So, there you go. If you have any questions or my descriptions are clear as mud, you can pm me and I'll try to explain further.
