Ron - Welcome to the ARF forums!
Not really a transistor radio, it's a CB that sold for about $120 new. Take a look:http://www.cbtricks.com/radios/lafayett ... /index.htm
It appears in Sam's Photofact CB
-41. - There's a manual available here for $10:http://hotspotcb.com/books.html
This fellow has one new-in-box. Perhaps he can scan the owner's manual for you"http://www.kightradio.com/item.php?item_id=225
RadioMuseum says this runs on 12V. - That would be 8 batteries @ 1.5V each:http://www.radiomuseum.org/r/lafayette_ ... com_2.html
Hope that helps!
