Late 1800s weighted balance scale with sliding pear shaped weight.  The head is marked with the number 100 - P. Rogers - Warranted. The sliding shaft is notched in 5 lb increments on one side and 10 lb increments on the reverse.  Increments are kind of hard to read but they are there. Has a double hook on the end and 2 single hooks above that.  It has light rust all over but should clean up better with a wire brush. Measures 20.5 inches long the head where it is stamped is 2 inches across. I picked Priority Mail because it should pack nicely into one of their shipping tubes.
