please ID these chairs  

Hmmm
Are they?

Grrr I know these from...
Grrr I know these from somewhere, look Meier-ish but they arent...Will rack brain and have a look.

They look like Joseph...
They look like Joseph Hoffman Fledermaus chairs.

.
yeah they do look a bit like copies of that chair, I saw about 10 kubus chairs going cheap in a shop a while ago but the leather was blue and would have cost a packet to get even 2 redone. So maybe they are being targeted if such things are turning up even here.

.....made after
Style = Wiener Werkstaete
after Joseff Hoffman
Definetly not the real Mc. Coy though upholstered with WW material could fit in a Jugendstil(ish) interior.

...and
they were first used in a bar in Vienna around 1907. This bar was called " der Fledermaus " (the bat). That is why this chair is still called the fledermaus chair. I have to say that your chairs look roughly like them, the original has more detail. F.e. wooden 'balls' in front under the armrests and seats.
