Carhartt makes plenty of tough work clothes..they are no where near levis...their full swing coats are fantastic. If they cost too mugh buy irregular, or the 40 percent off sale carhartt has every end of season.
If someone really wants old carhartt, ebay has tons...all sizes and conditions.
you did well the jaws look intact.. i only have one parker so im learning about them a bit, but they are well made. give it a nice bath in paint stripper and pressure wash
