Timeless Tools and Treasures

One of my customers brought this item to me at the Peterborough Antique show. It is missing some parts, but we would like to know more about it. It is marked “Howe”, a company that still makes industrial scales. It appears to be brass or bronze. It is 43″ long and 7″ high and marked to accommodate up to 2,000 pounds. Most towns in New England would have a scale like this for weighing hay and other items. However, I have not been able to learn anything about it from local source or on line. Any information would be appreciated.
