Invested in friends failed Brewery

I invested a small amount of money in a couple of friends brewery about ten years ago. They were forced to close at the end of last year. The two majority owners had a falling out and aren't speaking. They both put more time and money in than I did but they have both been less than forthcoming with any details. What questions should I be asking? They have equipment to sell and have already begun liquidating assets. I'm honestly unsure if there is anything left and if it's worthwhile to contact a lawyer or just write it off. My $10,000 investment got me a 2% stake... I can't imagine they even have $50k worth of stuff to sell based on the saturated market with the number of local breweries that have closed recently. So yeah, what should I be asking these guys? Friendships aside.

Thanks! Thought I was a good friend, apparently an ignorant investor instead!
