Identifying a pair of danish-style armchairs  

I just picked two of these armchairs for £3.00 EACH!!! But unless I can find out a little more about them, thats about all they will be worth.
They seem like they are almost original in condition although I think the covers of the cushions may be later additions. The base has leather straps for support running front to back but not left to right - one one chair they are all there, on the other there are only two left. The previous owner has added a plywood bases to save from falling through them. Other than that, the frames look good, small gluing repair on a couple of bits but thats it.
BUT
I can see no branding or makers marks ANYWHERE on them, not even on the leather base straps.
Can anyone identify the maker from the pictures??
