Fairchild AN-N6 Gun Camera

After my visit to the Bottisham Airfield Museum at the weekend and spotting their AN-N6 camera, I had another internet search to see if I could find one at a reasonable price. 

I did, and it arrived today...

It appears to be in good condition and came with the screw in lens filter and a film cassette (trying to work out if it contains film!) and the serial number appears to match cameras produced by the Morse Instrument Co. Hudson, Ohio in 1944.  It also carries a service/overhaul label with a RCAF reference number dated 1957.
While the camera is roughly the same width and height of a G45 it is approximately half the length. I'll post a bit more on the two shortly. 

UPDATE: Opened the film magazine and no film - also some internal parts of the magazine are missing so might have to try and source a spare mag from somewhere...
Also, picked up some 'acorn' dome nuts to act as feet on the mounting bolts. 

UPDATE 2: Now have a complete (unopened) film magazine with expired film so have cracked it open to work out how the film was fed.
