I think the sides, top, and front pilasters, were finished in something close to the "Extra dark walnut" in the Mohawk line of finishes. The wood underneath is poplar, maple, or some other grainless wood so there really isn't much to see. Oil stain is a waste of time, it looks blotchy, I have a 620 refinished that way an I eventually want to redo it the correct way, as well as re-veneer the front panel, aniline dye stain might do the trick even though it was never used with any radio cabinet that I know of.
Best Regards
