One was the British Airways Dove Livery (G-EUOH) and the other was the famous British Airways FireFly (G-EUPC) (G-EUPC has now been repainted back into the normal British Airways Livery which is a massive disappointment to a lot of people)
The models which I bought are on the scale 1:400 (quite small) but they are of get good quality. You can find them on eBay from a seller in Hong Kong, however, I bought them from Aviation Megastore for about £20 each.
The models have great detail and are great quality. They are metal models and only come in the 1:400 scale at the moment.
Here are the links that I got these models from. They may have sold out!
