Vintage Doucet Tandem

Hi I picked up this old tandem off of craigslist one day and I am baffeled, can't find any info on it, it is very unique to say the least, says Doucet on the Head badge says fabrique garantie on the down tube so I am assuming it is French or Canadian. It has one brake lever with a double cable, one goes to front, one goes to back, it has very old looking leather seats, some kind of generator, and something that looks like a light or siren on the front, the back of the frame has a cage that goes over the fender and has what looks to be a place to attach a trailer. The rear derailleur looks like a spur off a cowboy boot. I would love to know more about this bike before I decide what to do with it. Any info would be greatly appreciated, I have more pictures but they only let you put 4 here
Thanks
