Cool stuff and keep digging!
Here are four pre 1965 ads that may help w/ more clues, all are '63 Tankers also geographically close to Ohio.
Note the 04/64 Go-Power Becker Auto Sales ad Z-06 w/ Sebring Paint, are there other Silver '63 Tankers w/ Indiana history or anything known of the subject vehicle ever being there?
I have 25+ Midyear Tanker ads saved to post here in the Old Newspaper Ads thread but if you're involved w/ other Tanker guys,
grab some stars/join the SYC and I'd be happy to pass them on to a club member first.
Let us know if we can help any further and best of luck w/ your quest!
