Need help on identifying a teapot

[AliceT]

I recently bought this teapot, but I'm unable to identify it.

It looks French in style and the makers mark also looks french in style but doesn't have a sharp lozenge shape outline, the top and bottom line look more rounded.
Apart from the makers mark it has 2 other marks that seem to be the same. They are rectangular marks, and could possibly be the weevil marks but I'm not sure. The latter 2 have bicorne marks on the opposite side of the marks.

The teapot:

The makers mark. Two letters with a swan in between. In this picture the letters look like 2 J's, but irl the last letter looks more like an E or F.

The 2 other marks. The first one is placed on the rim of the lid, the second one is placed below the rim of the teapot.



Sorry for the huge black borders around the last 3 pictures, but I couldn't get the pictures uploaded without them.

It's not French, but German. The last letter is a "K", and it's the mark of Johann S. Kurz & Co. of Hanau. The company was founded sometime before 1870 and was still in existence in 1961. The ant, however, is a French import mark in use from 1893. I think your piece probably dates from the first third of the 20th century.

Many thanks blakstone!
It's odd that it lacks other German hallmarks.
