Hi Mark,
I am not sure what the scale of that model you have attached is. However there are a number of manufacturers of various models of the very small scale of 1:1250 available around the world.
You could try Mercator for a start. just place the ships name and the scale you are looking for and some data will come up. The cost of the Oriana by Mercator was 4 times that of the model you are inquiring about (Cost wise.)
Good luck Greg
