Spoke to the guys at Debben this morning (as I've had my manual CCT's on order from them for the past few weeks). Whilst they don't have any in stock, was advised that they are still awaiting some to turn up from APE in the US - however, given they don't know when they might arrive they are taking orders (and like me have others awaiting some to turn up), and they have enough now to get a batch made locally (which they have done before apparently) which are as good as the APE ones - hopefully they will be available within the next 2-3 weeks.
So if anyone is thinking of ordering some, may be worth giving Debben a call, as they will increase the size of the batch being made (if they go this route cos the APE ones are in short supply).
