Here we have an old OPPERMAN GEARS LTD reduction transmission or gearbox. It's a type B-H with a 21-1 reduction ratio (see photos) . It turns very smoothly with no play or movement on any of the shafts. The bronze / brass worm wheel looks in superb condition (see last photo with the oil filler screw removed). I have no idea what this reduction transmission was used for (maybe Industrial, Agriculture or even Military use ?) but it's a nice looking and interesting object !. Please enlarge all the photos and have a good look at the item and condition for yourselves as they form part of my description. Please note if i have to post it i will naturally have to drain the oil out of it. Any Q,s please ask.
