The Lone Star Models kits are for the most part 1:192 scale (1/16 to the inch). There are a couple of 1:72 scale kits in the series - notably the submarines. Mike West of Lone Star recently sold the masters and all rights to his kits to Rusty White of Flagship Models. Rusty is in the process of refurbishing the masters and re-releasing them. Most will have new photoetch that was not originally part of the kits. Flagship is a PE company that is branching out.
I've built several of the Lone Star kits. My favorite is the USS Winslow torpedo boat of Spanish American War fame. For the most part - the Lone Star kits are whole hull and their method of construction allows the modeler the flexibility of constructing them waterline if desired. Generally there is resin, white metal, perhaps some vacuform, and chain.
Details vary. The USS Monitor, for example has a solid turret. The guns are just muzzles and are cemented to the gun ports. The Hunley was originally done as the model outside the museum in Charleston. After the Hunley was raised the model was reworked based on the new information.
Some of the kits, mostly the sailing ships, are vacuformed hulls
In 2004, IPMS North Central Texas built all of the Lone Star kits for our group entry
This is just some of them -- can't quickly find images online ... The USS Osage (upper left) is mine. It is not a LSM kit. It was scatchbuilt.
