Does anyone have a reference on diagnostic features of historic lead
sinkers (line weights)?  We recovered a split-barrel lead sinker in the
upper 10cm along a river terrace in southeast Idaho.  Modern debris as
well as debitage were found in the same level.  The sinker has flanges
or pins at the ends of the barrel that fold over the split seam to
secure the fishing line.  It measures 1-13/16 inches long and is 5/16
inches in diameter.  Thanks in advance for any help.
