my VIVALP Grille Tout Pain (electric "all bread toaster", from France)

Here's one of my kinda more-fun (I think, anyway...) small electric kitchen appliances. I can't say I've ever visited France, but apparently this is a not-uncommon form of electric toaster as found there, at least ca. 1980's. Given that the French are rather well known for their wide and fine varieties of fresh-baked breads, it sorta stands to reason that a machine like this might be slightly more practical over there, than the ubiquitous USA '2-slot popup' toasters designed for the generic slices of wonder-bread we endure here...? I have had it since the late 1980's myself, after saving it while helping friends clean out the (former) home of an an acquaintance who's wife was native French. [and nobody else recognized it/knew how it worked either, thus they didn't want it?? <lol>]

Made by VIVALP, it has two coiled heating elements inside which both radiate their heat rather indirectly (and in a slightly different fashion) to whatever food item is placed on its rack. (pic4 sorta shows 'em glowing, I hope?) Finished in white with red accents (my favorite color scheme for such things!) it has a 3-position rocker switch that seems to choose between the most indirect element/off/both elements, and a combination turn/push dial which seems to perform a start/timer function. Having not ever had an actual 'instruction book' for it, I'm still not certain if I understand how to operate it correctly...nonetheless I find it very handy to toast hamburger buns and poptarts, at least...? ;-) :-) It measures about 13" across its front, and does not have any labels/ID on it beyond what is shown here.

If anybody can tell me anything more about it PLEASE SPEAK UP -- I'd love to have a better clue about what it actually is and/or how I should be using it...?? <LOLOL>
