Had a Mark X Mauser in the early 80's with wood that looks R50's shotgun.

Messed around with it off and on for a couple years (had no clue about anything much less stock finishing) finally hung it up with some all thread and took pops rosebud torch to it. Can't remember what paper I used after the fire but got it smooth again and smeared some sort of furniture finish on it. It looked so much better my hunting buddy thought I'd traded it for another one.

I do remember cleaning what passed for checkering up with a homemade tool. I'm sure that was a bubba mess.

Like R50, trial and error is my teacher along with the innanet now.

Wish I'd kept the Mauser, it shot very well. Had to go to fund IPSC stuff.
