I'm almost 100% it's an Adam forearm from the 1980's. They made a lot with straight maple forearms and rosewood or similar points. The other ones that look the same by KPS Taiwan had thinner veneers. I'll see if I can dig up a sample and photo it tonight to compare.
A lot of these forearms are high quality and very difficult to tell from those made by Burton Spain. Even Tascarella converted some, Palmer bought some good ones (and later on , some stinkers) from overseas. The Adam ones were head and shoulders better than anything else coming from Asia - no comparison.
