Welcome to the Phorum!
Probably a 1970's vintage and it looks like Sams Photofacts has a schematic for it for $22. As far as value, some of the others on this site are more familiar with this vintage so I'll let them suggest value, though I don't believe it is worth very much. They are so big and cumbersome that they are hard to even give away. Thus the reason its still in the attic of the house you bought...but I could be wrong..
