Fechtsport Langenkamp should also be able to get you parts for both
Uhlmann and Allstar reels.
In the U.S., Blue Gauntlet provides the Uhlmann reels used at NACs and can get all the parts for them (some might need to be back-ordered), although for a higher list price than from Langenkamp. If it's a small item that they have in stock the higher mark-up may be less costly than the shipping from Europe.
Also, some of the little bits are standard metric parts that you ought to be able to find at a well-stocked hardware store (e.g., the screws are metric 3-mm thread). Was it any particular part that was needed?
