I'm looking to rebuild a 2071 scale (needle stuck at 34lbs) and I'm not familiar with these scales at all. I was hoping that somebody here has a source for a owners manual or an adjustment guide so I can get her going again. It looks like it's in ok shape, the inner fulcrum looks to be off track and I assume that's why it's not working. The glass and all the needles are fine so I'm assuming it just needs put back in working condition.
