WTB Dealer Radio with Lotus logo

[Sherman Kaplan]

Back in the late 70's I had a 72 Europa Twin Cam.  I remember that some of the dealers sold a radio with the Lotus Logo.  As I was in college at the time it was enough that I could borrow the money from my parents to buy the Europa so I could not afford the radio.   Now that I'm a little older and refurbishing a 73 TCS I would like to try and find one of these original radios. 
I can't remember if they were 8 tracks, cassette or just am/fm.  Does anyone have one for sale?

Thanks,
Sherman
