This is a left and right window regulator from a 1933 or 1934 Chevrolet car or other GM marque.  The handles are for Chevrolet on one of the sets with one of them missing a spring. Another set has no handles but has a pair of good springs. Another set has no handles but one good spring and one MIA spring.  THEY ARE STUCK!  Need disassembled to get them to work.  They do not and refuse to turn as they are.  There are several more sets of these.  The arm centers are 10" and gear centers are 3 3/8".  Missing one spring.  Wood will be removed before shipping. PLEASE INDICATE YOUR PREFERENCE WHEN ORDERING if it matters.  I have  a LOT of these mechanisms with one thing in common, that being stuck that I will be listing at low prices.  The handles are usually difficult to remove.
