I'm trying to remember what kitchens usually contained in my childhood. I can remember back to the very late 1970s, and I think then I would have expected: gas/electric cooker with grill (=US broiler, not barbecue!), sink with draining board, electric kettle, maybe toaster, washing machine, fridge (with small internal freezer compartment) and not a lot else. Tumble dryers would have been rare, I think. I'm pretty sure most washing machines were automatic front-loading models, looking superficially like the modern sorts, by then, but I'm less sure about 1968.
