Can anyone ID this tube as far as the maker?

It has long grey plates

Thanks

Is that batch/date stamping near the bottom or just a sharpie pen from someones testing results?

Can't quite make out the letters/numbers

Here'd a couple more close ups

One is a hand written and other possibly stamped other someone with a really steading hand.

Those codes do look very similar to european codes and the stamping, the tall font looks a bit like some Brimar or the Mazda branded Brimars

How's the brand?

May be it is a 1958 Philips (from Holland)

Consider the prints

Yeah, the construction does look very much like Philips type, the mica spacers and plates
