Includes:

Two lasts with high heels which appear to be of some sort of burl.  These are unmarked and very rustic.  This style could date to the 1830's. 

A last by Western Last Co., St Louis.  Western Last was in business from the late 1800's until after 1940, when the company provided boots for WWII soldiers.  

A Chicago Last & Die Co. last with a metal plate on the soul.  Chicago Last & Die was in business as early as 1892 and as late as 1914.

An infant shoe last, date unknown

A foot-form, patented in 1907

A shoe stretcher by Cox-Willcutt & Co.  The company was formed in 1861.  Willcutt left the company in 1865, but I believe the company continued under that name until the 1880s. 

An undated pair of shoe stretchers, probably 1900 to 1930.  The metal mechanisms work, but one is very stiff.
