Hi Jean-Pierre,
The Just For Dinner Bread Machine by West Bend makes a 3/4 lb loaf. They aren't making that model any more, but here is the manual for it, including 27 recipes. I think they'll be a good fit for your breadmaker:
Westbend Just for Dinner Breadmaker Manual and Recipes (West Bend site)and here's another version of the manual that includes recipes from the previous manual plus three additional recipes - Sunflower Oat Wheat Bread, Wheat 'n Vegetable Bread, and Honey Cinnamon Wheat Bread:

Happy Baking!
