Vintage Sectional Post Binder Equipment

Description

Post binder screw posts for accounting ledger books, normally used with a 2 post binder.  Extensions and wrench as shown in the photos.  Several different lengths, plus one can be screwed into another for a longer extension.  Each post has a round hole that you use the wrench to tighten or untighten the post extension.  Vintage, probably from the 1960s and in excellent condition.  Saves you from from purchasing an additional post binder; instead just extend the posts in your existing binder.  Assume these are 5/16 inch in size.  These are not the light-weight aluminum screw posts that some photo albums use, instead these are heavier metal, maybe steel.
