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.

Hi Peter.
I am in no hurry, so we can get back to it...
You could try asking Cooke, they are still in business (although now split from taylor Hobson), but they are now heavily involved with making cine camera lenses. There may well be a retired employee who could tell you what the problem is likely to be. Those lenses were still made in the 60's and possibly 70's.
