Wow, sounds adventuresome! You can read some unpleasant things about civet.
Years ago my brother wore something called "Civet Oil" by Houbigant. It smelled really good and I was always ticked that he found it first. :'(
They don't make it anymore but I sometimes catch a similar note in a fragrance and just assume it is "civet". It is a warm and sweet aroma and surprisingly subtle.
Good luck with your find, it just might be a treasure.
