Definitely the same bass...
Told this one before...
When I went into a local haunt to buy my own first bass (a Grenn EB2 copy), there, on the wall, was this beautiful cherry and gold Thunderbird, priced way above my budget at £200, but I could look...
Anyway, about a year later I went back into the same shop to contemplate number two and there was this white EB2 (may have been a Rivoli - further research discovery) for around £200 but I was short of this so I went to visit the Bank of Dad, who agreed to enhance my funds, so back I went, and the EB2/Rivoli was gone, bought by Bruce Foxton earlier that same day... gutted...
Well, I turned to go and out of the corner of my eye I spotted the same Thunderbird, back up for sale, having come back, now a "third hand" offering... and £20 cheaper than the EB2... sold, thank you...
The beastie has remained with me for the last 37 years...
