Inlay material?

[Cold Spring]

Recently I found a Super-Fox that came out of Texas; the barrel fit was a little loose and as suspected it turned out to be a broken yoke (the yoke actuates the rotary locking bolt). Finally I had time to disassemble and will replace the yoke along with doing some other work to get this Super back over the water this season.

This Fox has some simple inlays and the inlay material is hard and dense as could be. Inlays have some lighter and darker areas along with a layered "grain" as shown in the second pic of the grip cap. They don't appear to be wood but I could be wrong.

Any ideas what this material might be? Please click on pics to expand them. Thanks.

PS: the duck inlay is purely decorative/artsy and isn't covering a repair dowel or pin. Stock is off to access the yoke and mechanism and its head inlet cuts are tight and without any cracks or old repairs. The hammers, trigger sears and innards are coated with oxidized/hardened grease and the frame is solvent soaking now.
