Tannoy Definition Tower Speakers

They don't look like the ones on the link. Where on the speaker would I find the model #? I just see Tannoy Definition at the back bottom.

The front of the speakers are half covered from the top down. Solid the rest of the way down. They stand about 4ft tall.

What size are the drivers?

DC10?

There are several generations of Tannoy Definition speakers.

Google Images Tannoy Defintion and see if you can find a photo that matches.

I finally found the image that matches the front and the back silver plate. They are DC10t and now I need to know what to ask for them in the estate sale or online. Some were sold lately on one site, but it doesn't say what they sold for. Does anyone have an estimate of what to ask for them?

Thank you for your help!!
