Coffee/chocolate/water jug

Can anyone help identify the maker and date of this?
I've messaged the only Master's & Co in London that looked like they'd been around for a while and am waiting to hear back.
As well as what you can see printed, 1925 is pressed into the base - don't know if that is a year or mould number.
And what's that spout groove all about?

Actually, google has just helped me - Bauscher Weiden - but what about that groove?

It looks like the type of things that I used to see years ago that had insulated jackets covered in metal.

Yes. WMF covers apparently. From the photos I've seen, it looks better naked.

Even back in the day when the metal covers were trendy, I thought the same.

Here's one with it's clothes on: https://www.liveauctioneers.com/item/92557360_deco-wmf-cozy-and-bauscher-weiden-coffee-pot
I think it's a drip-proof spout. Try it.
