I see the prices of these are all over the place- could you guys give me a rate from 1-10 and the value. thanks old gas

I would value around the $1800-$2000 range.

...there was one on eBay recently in similar condition, that sold twice (the buyer bought it, relisted it, and it sold again)...should be able to get an accurate read from that...

7-8 rating $900-$1200.
