Help I.D. Roadmaster

[Evans200]

Sorry no serial # available. This is a ebay bike I'm considering. Owner knows very little about it. Currently has middleweight tires on it. I'd like to know:
Year: As close as possible.
Middleweight or balloon tire bike?
$ Appraisal in your opinion. Asking price is $675 OBO, plus shipping.

Thanks everyone!

To high mid 50's balloon tires for sure lights wrong too. To me no more than 300.00 if I sooooooo needed it
