Where is this hair?

[Xícara de Café]

Dear forum, My F2 consistently shows a hair-like object at the bottom of images towards the left. It appears in a Loch Ness monster-style series of ringlets. I'm unable to see any dust or fluff when I look through the back or the front, or when I lock up the mirror. I've used a blower on various occasions to try and clear it out and the hair appears no matter what lens i use. From this typical image, can anyone say where in the camera I'm likely to find this hair? Thanks! :

Same on all lenses?

Yes

I beg your pardon everyone, please ignore. I found it and I think I've removed it. Needed to use a magnifying glass....

Where was it? Given how "sharp" it appears, I'm guessing it was located somewhere in the film gate/near the shutter.

[Xícara de Café]

Yes, exactly. It was on the upper side(?) of the gate I think. Could only see it from the front with the back on and with the shutter open on bulb

[ben_hutcherson]

Upper right would be the correct location-remember that the image projected on the film upside down and left-to-right.
