Topline was the name previously applied to the old Jackson models with eye level oven-ette. They revived the name for this late 1980s more conventional cooker, pitched as an alternative to the Belling Format
UK manufactured (the earlier Moffats were Canadian) and based on the Tricity 21" wide range of cookers - Tricity was within the same group - two ovens and two grills (broilers).
This is contemporary with the 21" version above, but in this case there was no Tricity equivalent and indeed this model would have been more TOL than the 21" My recollection is that, as well as being wider, its also rather deeper than the 21". Large main oven with oven-ette. I always like these, if it were not a bit far .....
And definitely 1970s. That dishwasher placement is highly unusual but could well be original (dishwasher is not) as the cabinet is a bit large for a conventional oven and the opening looks too small for a Moffat Oven. I quite like the open shelves/dresser effect
At first glance this kitchen does not look all that much, obviously good in its day, now it bit sad. A closer look at the wall cupboards shows that it is a, seldom seen, Multyflex kitchen from the early 1970s. The handles on the base cabinets must have been replaced at some point. Where the fridge is would have been a built in model. One has to wonder about the oven, it looks good but that the control switch is all taped over indicates that there may be a problem somewhere. The ceramic cooktop is not original
