Today, there are almost no molds made anymore from wood.  They are either made from plastic stock or metal.
This mold  is from an age of days gone by, where most patterns were made from wood.
Pattern making is a  highly skilled trade that required a lot of handwork years ago, now most everything is made with CAD CAM machines.   Pattern making required often working within 5/1000ths of an inch, and was one of the highest paid trades.
My father is winding down his 50 year pattern industry business, and this came from his pattern archives.
Specifically, I do not know what  this was for, it is old enough that records are no longer available to identify  it.  It was for some large piece of machinery.
This was the original wood mold, my fathers' business was subcontracted by a  foundry to make this original mold.
Made from solid mahogany, left natural color, varnished.   My fathers' shop either painted all red, or left natural wood

Overall  very nice condition.
