Good condition.

Idle gear hairspring for the idle gear on the base of the camera.

Fits Olympus OM1, OM1N, OM2, OM2N, OM10, OM20.  Might fit other models, don't have any on hand to check.

Choice of Special Delivery (next-day) or 2nd Class postage.  Postage is actual postage cost.  I will post out same day if there's time, otherwise next day.

International shipping also available, by Royal Mail International Standard.

I will leave feedback for you straight away when you make your payment.  My feedback is exemplary and I intend to keep it that way, so please purchase in full confidence.

Also selling other Olympus items.  Will happily combine postage.  Just go ahead and make your purchases, then leave me a note when you make your payment, or message me directly, to advise you have purchased multiple items.  I will then refund the excess postage.  I usually notice such purchases anyway, so would automatically combine the postage and issue the refund for the excess.  I think it's easier if you use the "add to basket" option when purchasing, then pay for all your purchases at once.  Either way, no problem.
