RCAF Navigation Computer

[gbalke]

I hope this is the correct forum for this, it's another piece of my WW II RCAF collection. A 1935 dated, Type E-6B navigation computer made by the Stanely Manufacturing Company.

Hi:

I found a similar item this weekend in my Grandma's things. My grandfather was a First Sargent in WWII and he was a gunner in a Boulton Paul Defiant. When they where discontinued he was moved to Labradors. Anyway here is a pic of it my dad took with his blackberry.
Do you know where I can find out what it is worth? We are trying to clear out my Grandma's things as she is moving to a care home and I know it is most likely valuable so I would like to have my Dad to insure it and keep it.
