The interior and cab look quite like Howlite from Tick Canyon California. The exterior, not so much.
Howlite is a really soft stone, like 3 1/2 on the Mohs. Should be super easy to tumble.

Thanks for the evaluation Capn Bob. I packed my hardness testing kits already. Harder than a copper penny and similar to steel a tad softer than steel in my estimation. Based on that, the chaulky white could be Tick Canyon Howlite; sure looks like it.. I have not tumbled any; just cut a few slabs and Cabbed. The Agate like material is harder than steel, probably an Agate. Charlie
