The clue for me: It was a "closet camera" for 10 years.
I'd bet dollars to donuts that a sluggish shutter is the "oily magnet"
problem. It's the classic situation (stored for years) with the classic
symptoms.
Try firing the shutter several hundred times (without film) in rapid
succession . . . using a manual adapter at 1/1000th if you have one for
it. If the shutter seems to improve to normal, leave it wound (shutter
cocked) overnight. If the problem returns at least partially the next day,
fire the shutter again several hundred times and see if it improves
again. If so, this pretty well confirms "sticky magnet." If it doesn't
exhibit this behavior, it's still very likely a sticky magnet as you can't
conclude it's not from this. Cleaning the magnet is not that difficult a
repair. Very likely it could also use a foam door/mirror seal replacement
as the foam goes gummy or dry rots with age. Also not that difficult a job.

Having used two OM1N's for the last seven years, I have thought of
resurrecting an early OM10 that I have had since 1980. I understood that
this model and vintage had a fault in its circuit board that shows up as
longer than expected shutter speeds. This would occur for me both on auto
and also on manual. Is there a circuit fault, or is it just oil on the
shutter magnet as mentioned by John Hermanson in Camera Repair FAQ? Not
having used it for 10 years I have retrieved it from the cupboard and it
sounds as if it is behaving, I need to put a bit of film through it to
verify. If it were oil its probably dried up by now!
I would appreciate opinion on this as the local agents told me that it was
not repairable. Resurrecting this would give me more time to look for a 4Ti.
Thanks Allan.
