This turn coordinator is complete but does NOT work, it would need to be overhauled,The off flag also does not show in the window. I purchased it  and was going to send it to Aircraft Quality Instruments for overhaul, they charge $325 complete with paperwork 1-800`942-9938. Instead I was offered a deal I could not refuse on an already overhauled unit so that is why this one is on the block again. Model # is ANS-60. Shipping of $15.75 to the US.
