It seems like you have some experience with these. Can you say to your knowledge whether any of those bolt-on neck Epiphone's had solid wood tops? The Epiphone wiki seems to imply that various ones did.
Some of the guitars it flat out says solid woods.
Here's the page for the 6700/6800 series guitars: http://epiphonewiki.com/index.php/1970-71_Model_Series#Model_6834_12-String
And here's the page for the FT series guitars. http://epiphonewiki.com/index.php/FT-Series
Taking the FT-155 for example, it says "Solid spruce top".
