I would love to, BUT: I am in Brazil right now and will not be back in Holland before July this year.
Cost: shipping cost only.
On the other hand: if you can measure the one screw of your older Cook and one from this lens and send them to me, if posible pic's of them.
I have quite a bit of tiny screws here in Brazil, I could send you some by mail at no cost.
I am in no hurry, so we can get back to it...
