I think that is the old Suntour Le Tech front derailleur. I really liked that derailleur, it is high normal. Thus, both levers go the same direction, forward for higher gearing and back for lower. I use that on one of my touring bikes and I would use it on more bikes if it would fit. But some of my bikes have too little room between the rear fender and seattube for that derailleur to fit in the space.
Don't load it up too much, the smaller diameter down tube on the older classic bikes could mean a lot of frame flex with a load.
Always make sure your front brake cable is always in good shape. Without a fender, the straddle cable on the front could catch the front tire and lock up the wheel.
