I got an arm on an old Oak Audio deck a while back. It looks like the one on this thread asking the same question.

It's similar to an LMF-2 or ALT-1 but not the same since they have the anti skate under the arm rest, not at the side and a different bearing housing.
Any ideas? Sounds decent with an XLM III on it.
Thanks
