The rest I believe are possibly purpleheart. Tough to know without scraping them. You can remove the bumper & use a utility knife to cut a small sliver to see the natural color of the wood. If it's purple then it's purpleheart. If it's kinda red then it's mahogany. If it's pale brown then likely walnut. Cues that old fade so much they all look the same. Purple turns pale brown and walnut lightens. Both look like mahogany. But a small sliver cut from under the bumper will reveal the true color & that'll help identify the wood.
A brazilian rosewood 26 1/2, or Titlist, is a really great find! Purpleheart, too, but not nearly as rare as ebony, macassar, or BZRW.
I have a PH Titlist conversion. Lightnin' in a jug. I was very lucky.
Very cool.
