What you have here is a hull with no subdeck, deck hatches that just sit inside the fiberglass hull with the most basic superstructure, and internals + radio that are 20 years old and would need to be gutted and replaced to be even remotely competitive in modern combat. This is $300 at its best, because there is a servo + bottle + hopefully a regulator + some BC cannons that might be serviceable. Oh and a black base BC pump.
Someone else who recently parted ways with their fleet gave me an Espana hull (uncut) with similar aged components as yours to drop in as a bonus on another ship I purchased. The old components are going to the museum and the hull will be paired with as many modern internals from my overstock as the buyer requests. I MIGHT get $200 to cover my time, travel, parts, labor for cutting if requested, etc. New guys don't want old tech. Old guys don't want to go backwards in time.
