Welcome to the forum! I agree, pics are definitely needed.
As far as I know, the maker of trunks this age isn't particularly important when it comes to value. Unless it's a big, well known name or something. Dome top trunks in general aren't worth very much right now, and even less if they need work like you say yours does. I'd say an average-maker trunk that is in need of serious restoration is worth about $50-$75. In good condition, about $200. I'd love to see yours though!
