1940s unmarked elm chairs  

Hi

Picked up a pair of these chairs at an auction in UK last week. They look brutalist, but I know that’s a term that’s bandied around a lot 😉

We’ve a few bits of mid century furniture in the house such as Troeds, Ercol, Ladderax etc, and saw these at auction house and took a punt.

No maker marks as far as we can see, wood looks like Elm - but other than that, I’m stumped.

A similar pair were sold here but unfortunately no clues to the maker

Has anyone seen these before?

Thanks in advance
