This is a vintage or antique Richenbacher ACE bakelite lap steel guitar. I have tried to research the age on this but i could not determine anything specific. My guess is that it is from the 40's.
It is missing strings and a couple of the fret dots are missing. The spelling of richenbacher changed from a ch to a k in later models. The original case is pretty rough.
The bakelite is in excellent condition. There is one scratch up near the tuners as seen in the last pic. I unscrewed and took off the back for a pic in case that helps you date this. I just plugged this into my bass amp and sound comes out.
