Possibly recycled UHMW? It can come in a dark muddy or yellow color..

So is that the full pattern? Is the interior pocketed out and used as
the mating pattern for the part? [Instead of two patterns?]

Jarrett

Jarrett,
The material was still a mystery... so we did the specific gravity test. It
floats in water, so is most likely recycled UHMW. Unusual color for this,
but almost no other plastic has this density.

Where the H@LL did you find a chunk THAT big? For free no less..
Crazy... I pay many dollars per sqr foot of 1" stuff..

Jarrett


Jarrett,
The chunk was 48 x 60 x 7.5 thick....... should have seen us cutting it with
a sawsall. The business next door had it in their loft. It's been there
since they moved in 25 years ago. Original source unknown. They were just
happy to be rid of it.
