It's a long shot, but you might try contacting UMA Instruments.(umainstruments.com) They manufacture some really nice aircraft instrumentation and are reportedly very nice, helpful people who take pride in customer service. From what I have seen in articles and on their website, they may be the type of folks who could either evaluate and repair your compass or steer you in the right direction.

"steer you in the right direction" lol.
