Can anyone identify this as G Plan or other furniture  

Hi all,
I inherited this set from my family but they can not tell me much about it. They bought it around 1968 in Bristol England. They had bought a lot of G Plan furniture but were not sure if this was G Plan or not. It is a set of a sectional sofa, 2 chairs, and 2 ottomans. They arms come off to allow for arranging the furniture as you like. The base is teak I believe.
It is very comfortable and very well made. I'd like to recover it in fabrics from the era of it's origins.
If anyone can identify it I'd really appreciate it.
Thank you!
