I posted one of these a few days ago that I bought for $5 at an estate sale.
http://www.videokarma.org/showthread.php?t=252851 I sold it to a regular customer of mine that collects and restores radios for $72. The chassis # in mine is 18ZT40Z and the log book says copyright 1970.
$48 is a good price if you plan on keeping it. These go for hundreds on the auction site.
I haven't delivered the radio yet. I could scan the log book and send it to you if you'd like? Its assembled using the plastic ring binding and shouldn't be hard to duplicate at a place like Fedex Office or a local print shop except for maybe the faux leather cover with the metallic logo.
