EDIT: Reply from Irmscher Bits
Hi Nigel, thanks for your reply and your professionalism in not just relaying my message straight to the forum ... as a fellow enthusiast I do understand where you are coming from ... more so that an average retailer/trader would anyway.
Irmscher-UK do read members posts on anything concerning Irmscher on the boards, and have confirmed they've done so with this also.
Basically Irmscher-UK are not at fault and are in a tricky position when it comes to reordering any minority RHD specific parts from their German parent company. What Germany as told them is they need to order a minimum quantity of 100 units for another run to be produced which is obviously a profit gaining exercise from Germany HQ. But whichever way you look at it, its been a very slow moving part in the past (probably due to price) therefore Irmscher-UK do not want a large quantity sat around in the warehouse for ages, its not just dead money its probably other factors too.
As a backup plan, I'd recommend your members approach the Irmscher German HQ during the trip over there next year, and campaign to get the minimum order scrapped to let Irmscher-UK purchase whatever quantity they need for supplying the current UK demand. I think this may be a better long term solution to this and other part availability problems that may come up again in the future, in the end it will help Irmscher-UK, me and other Irmscher suppliers give you lot more choices. You are welcome to pass this message on to the Irmscher trip organisers if you wish.
Cheers for now ... keep working on the list!
