First of all: an immense Thank you to everyone! The response, though typically BC was far greater than expected, and gave a lot of purdy pics. I'm with @Unknown_User, coz this is fun!
As to Andy's proposal: WOW! Methinks that is a close as we're gonna get, and maybe if these existed several decades ago, this is the one I was in fact looking for even though I remember and saw it as more "rectangular".
Mind you, I've been doubting myself, as many different pics of Thunderbirds give many different impressions, and also they came in a plethora of variations - with for example different placements of the bridge (dunno how they do that - I'm no specialist in these models).
The thing I remember from that bass, and from what I thought I saw on the telly is exactly this character of obviously stemming from a Thunderbird but with the angles that count being closer to 90 degrees than in an original Thunderbird.
Andy's Rex does that exactly - to my eyes that is. Maybe you guys provably see it as much closer to a Thunderbird, Idunno.
Yes indeed. I fully agree with you there, and I did try both before and after posting.
Many of the programmes they show here in Norway can be seen online afterwards, but many can't. I've scanned what I can, but haven't found it. Should of course have made a note right away, but overestimating my memory is one of my weaknesses.
If the programme was Norwegian, you wouldn't be able to see it outside Norway - hence my attempt to play it online and make a screenshot.
Also, admittedly, my brain functions so unwell these days, that I might have seen an ad on my computer whilst watching tv - the bass being in the ad but my sick brain remembering it immediately as if the bass was on tv.
Therefore I've trawled my papers in the hope of a possible ad appearing again.
BTW, that would be Lord Bertie to you, but as you know I'm more of an Algy type. 😁
(Young uns: look it up! 🙂 )
Thanks, folks!
