"Acacia"...cause that really narrows it down lol
It is a cool idea, and I don't know of another hardwood dealer that does this. But I would feel more comfortable with the accuracy if it was coming from a long time IWCS member who wasn't also a hardwood dealer. I like Bell Forest. I think their wood is very high quality, but they don't come off as one of the more invested dealers when it comes to wood identification. I'd be more confident in the sample accuracy coming from Gilmer, for example. I know there is no standardization or verification process, so literally anyone could BS a name or make an honest mistake in identification. But I would think that would be less likely to occur with samples from Gary Green, XYLOS, or Mark.
I would also be more inclined to try buying Bell Forest samples if they weren't all such common species. I have wood matching every single one of those common names - some was even from Bell Forest. So it only makes sense to cut my own. And in fact, I've made it a point to try to source at least 3" wide stock for all new species I buy, just so I can cut a IWCS sample later on.
