Ingersoll back wind disassembly

[arron]

Good evening,

 

Doe any one know how to let the mainspring down on this guy. The winder won't budge.  Also, does anyone know of any resources specific to the back wind Ingersoll; videos, literature, etc.  I'm not finding anything.  I don't see a serial number.   Thank you kindly.  Arron.

Hi  The hand setter pulls off and the spring key unwinds poss Lh thread like an alarm clock, best to get the movemnt out of the case  and post another pic of the movement  then. It will probably be obvious when its out.

Thanks for the advice.  Once i took the movement out it was obvious.  Interesting though, there are two clicks so you have to hold both open to let the spring down.  boy was it wound tight.  Take care.
