probably wants restarting as a new topic.
Derek,
You don't want to get to hung up on the construction , as I have said earlier.
Wiltons are made on Wilton Looms as are Belgium Wiltons using the Wilton method.
The looms here constructing traditional Wiltons only allow 5-7 colours to be used the Belgium looms allow more hence the colours/patterns on the backs.
If in doubt Simply carry out the test below to be 100% certain.
You can see how easy it is for cleaners to be fooled by these types of carpets thats why I would recommend a carpet recognition course to all cleaners.
As for the burn test again no confusion here simply hold a sample of yarn in a pair of tweezers burn the end, if it shrinks back and beads it's synthetic . If it burns slowly and crumbles between thumb and finger it's wool or mainly wool (80/20).
You can of course carry out a float test to check olefin/polyprop (belguim Wiltons)
This will determine which type of cleaning to carry out regardless of synthetic materials used.
Any carpet that contains wool must be cleaned as a wool carpet even if its 50/50.
