ID help needed please - Unusual dining table and chairs, probably Danish. Designer and/or manufacturer ideas please?  

Any ideas please as to designer or maker of these items? For more images see this page on my website http://insightimages.co.uk/danish-furniture-from-1969/

All items were bought in Manchester, UK at Malcolm Bishop's gallery in 1969 or 1970. I think all are teak. The table is circular, 4ft/1.2m wide, but splits in half to take 2 solid extensions. The metal rails for that split are stamped Rosengaarden, although table is not necessarily by him ...and I cannot see any Rosengaarden tables like this one. There is a similar G Plan table but I'm guessing that theirs wouldn't have Danish extenders? Top of leg detail isn't like anything else I can see (I've been looking for weeks now). The dining chairs are also a puzzle: they may be same designer but are unmarked. They have pegged sides like an Erik Buch design, but there the similarity ends. Unusual profile to the back supports -as they are "U" shaped. Joints are very good quality. 'Leatherette' seats show virtually no signs of wear after 50 years of use. A Sideboard bought at the same time was by Dyrlund designed by Henri Rosengren Hansen, but I can't see a connection with these items.
