I have no doubt these are Habitat kitchen units, dating from a time when self assembly kitchens were largely in their infancy. At some point knobs have been added that were not originally intended - this was meant as a low cost, basic but stylish kitchen. With a bit more TLC it could be almost back to its original 1970s loveliness
Don't know a great deal about these, they were merged into the Radiation Group along with Jackson & Parnall but seem to have disappeared around the mid 1960s.
Doing these threads I have frequently posted Tricity President models, this was pretty much the last of the line in the late 1980s - fan oven and one halogen burner - the pinnacle of 1980s technology LOLOL Personally I much prefer the styling of the 1970s models
