I think that the B-H1 can also burn base-up.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Thats quite a rare lamp, normally these are always A-H1.

A-H1 is generally intended for use cap up only, and B-H1 is fot cap down use only. This limitation arises because the American lamps lack the platinum heat reflectors used by other lamps to keep the area behind the electrodes warm. Hence mercury can condense in the cold tip-off area if that is located below the arc, and American lamps therefore always have to be used with the evacuation tip uppermost. This required two different lamp designs.

Just uploaded a photo warmed up, about 15 minutes for full brightness. It is pretty bright, maybe 6000-10000 lumens. My camera's color balance makes it look green, but it is more blue like a clear modern MV bulb. It stayed in the startup glow state for several minutes, about a bright as a 40-60W incandescent. I thought it was EOL at first, but it just took longer than a modern HID lamp to warm up.

400 watts for 10,000 lumens! Technology has come a long, long way since then.

Yes, a lot has been achieved since the first of those modern HID lamps was introduced 87 years ago.
