ask Doug at Cameraland (gr8fuldoug or something like that) for his contact.
I needed a new objective lense cover for a pair of geovids a couple of months ago - doug gave me a contact (even though I did not buy them from doug).
I called and when the leica contact heard doug had referred me to him, i had not one but two replacement objective covers in the mail at no charge. Got them a couple days later.
