occupational daguerreotype harness maker? w/ tools of the trade poor condition

Description

I found this sixth plate daguerreotype loose in the bottom of a box at an estate sale on Wednesday.  The image was cleaned at some point and was sliding around the bottom of the box.  The mat, glass, and frame were also just in pieces within the box of junk.  There are scratches, etc throughout the photograph, but what a cool occupational image.  It looks like he is holding a thin hammer and what looks like harness equipment to the side.  It is what it is...amazing subject matter with poor condition.  Why can't I find images like this originally sealed?  100% daguerreotype
Please see my other auctions as I have recently purchased a collection of about 125 cased images that I will be listing over the next couple of weeks.  Thanks
