I think this fully flat base could just be an anomaly then. Everything else about it just screams MDG.
And we do know that they did do some unusual and experimental colour combinations.
As you know, John, there is that lovely heavy little pot with the flanged rim which looks Ming-ish in the grid pattern, but the strapping is actually green. So putting amber with blue should not be unexpected.
I cannot think what else this bottle could possibly be.
And while the base might not be the "battutto" thing, it's still not
fully polished which should discount it, but rough, which would be right.
