Chair ID.. Howard Keith??  

Hi, I've been trying to find an ID for this lounge chair for a while now (sorry the picture's so naff). I think I might be nearly there after finding a very useful old advert in House Beautiful magazine Feb 1958. I think it's by Howard Keith UK. But could be wrong..
From the advert, it looks like the 'L'alronde' chair, with the legs from the 'Escort' sofa... What do you guys think? Well, it's the closest I've come.
Please also see a photo of the advert attached in case it's helpful to anyone else.
Cheers
Stew
