As Alex C mentioned in a recent post, Richard Murrow published an article in the TUBA Journal some years ago that represents the best summary of academic work on August Helleberg. Search the archives. Bottom-line: Helleberg made a mouthpiece for each horn he owned. Even the mouthpieces he made for Conn were not one model per se, AIR. Your best bet would be to have someone custom make a mouthpiece based on your original Helleberg with modifications done to your specs.
