Hello there
Judging from the photo and the names you have listed, your models are not GHQ, they are the old Skytrex models which are now sold by Red Eagle Miniatures (
http://redeagleminiatures.co.uk/napoleonic.html).
The three decker in your photo is the
Victory (which I have). I presume the other one is the
Endymion, which I haven't seen, but your model is the right size for a large 50-gun frigate. The missing sails are the jibs.
The Skytrex/Red Eagle models vary in sculpting and casting quality. The
Victory and
Agamemnon are among the least good, but they are fine as gaming pieces. The
Salvador del Mundo is among the best. As Robh says, you can use the
Athenien models as pretty much any Spanish or French 3rd rate of 64 or 74 guns. I use mine as French or Spanish 64s.
Here's the Battle of Grenada in 1779:

Le Sphinx is the
Athenien model, while the
Yarmouth is the
Agamemnon model. You'll see that I lack the skill or patience to rig mine properly.
I wrote a review of the
Athenien model here:

If you really want to put a lot of time into building beautiful models, you might be better off buying a few of the GHQ models, which have the most accurate hulls, or the Langton models, which have the best masts and rigging.
Robh has given you good advice to go to Langton Miniatures (
http://www.rodlangton.com/) for replacement masts and sails, ratlines and rigging guides. I think you can buy bases there too.
I hope that helps. Have fun. :-)
