That could be one of the most valuable mantels enneywhere.
Tiger stripe maple is very popular for gunstocks, especially on traditional muzzle loading long rifles.
Finishing methods vary but prep work can be extensive involving scraping with broken glass, wetting, scraping some more and again and again, then sanding with very fine sandpaper. Stripes are enhanced with very dilute nitric acid then stopped with an alkaline solution. Sanded a few more times then a favorite old time 'seecret receit' finish forumula is applied. Very beautiful.
