Just to let you know I've just had this response from Graham at LEE filters. Unfortunately it seems there is nothong that can be done to speed up your order, however he offers a full and frank explanation of the reasons behind the delay here:
"LEE filters have seen an unprecedented, and unexpected (remember how digital was going to remove the need for filters?) demand for their products in the past year. With the increase coming so suddenly, it had to take us time to react.
All LEE resin filters are made by hand, and it is a very skilled job. Increasing the production of resin filters can only be done by employing and training new people, this takes time and not everyone can do it. Since January we have increased the output of filters by 40% per week, but the demand in outstripping this increase considerably.
We are not a multinational, we have 10 skilled girls working in a small lab making filters by hand, we are part of a bigger group of companies who are then owned by a bank, so we do not always get permission to spend money to increase the output of a small cottage industry making camera filters for a relatively small profit each year. Money rules the world these days, and the bottom line is everything.
We will sell every filter we can make, so we are certainly not in crisis, but we do have a problem which we are trying to overcome. What we cannot do, to be fair to everybody, is act on individual complaints about lead times. We strictly work on the oldest orders in the queue, to ensure that the customer who ordered earliest gets their filters first - there is no other way to behave that is fair to all. I am sure that everybody who has ordered our products wants them for a reason, and it is not for us to judge who's need is greater and move orders up and down the queue.
The long-term outlook is good - we are changing some of our manufacturing processes and expanding working areas and hope to be able to up capacity considerably within the next six months to one year."
I hope this explains what's happening and reassures you that LEE is not in any 'trouble' financially or otherwise... I'm sorry, it doesn't look like they can do anything else right away.
I hope you still manage to have a fantastic trip!
