I can't identify the model from the photos in Blue Book and I can't find the name 'Ensemble' mentioned in the 'Mother List', which are our two usual references. However, I must comment on the condition. It looks like it came off the production line yesterday! Of course that doesn't mean that all is going to be perfect inside, as I'd guess it's 50 years old or so, but it does look well cared for. We can advise you on any TLC that it might require.
I'm sure one of our members will have a model name/number and date for you
And I wish everyone would post this quality of photo when asking for an ID.
