Well what do you know? I have what appears to my male eyes to be identical medium/bright blue 1:43 and 1:72 models, but I wasn't aware there was a teal one out there.
Sounds like we'll be gunning for the same model. But maybe I have an inside edge since I already asked the typical UK sellers to contact me in advance if they find them.
And I'm still on the hunt for that 1:72 Proton.
