And nice talking to you (and others) as well, Dirk! :kissy: It's indeed an interesting piece. I imagine the 1/4 L was added later.
I've looked through a few sites showing a lot of steins. I've seen a couple with similar heavy-looking bottoms, but nothing matching yours in other respects. This is the closest I could find - it looks nothing like yours, but it has a heavy solid bottom, low round handle, and cut pattern. Oh - they say it's mold blown - I wonder if that applies to the flowers, too. Hmph.
Looks so awkward with the low handle, like it would be hard to work the hinge to get the lid open. Intriguing piece.
