Tent (Blacks Constellation Cygnus) (Harrogate HG1)

Blacks tent.
Series: Constellation
Specific tent model: Cygnus
It's a spacious, 2-person tent.
There's is a working string of 3 lights.
Last used in 2009, I think.
It has been looked after but not used in the intervening years. I got it out at the weekend and put the fly-sheet up in the garden. The inside of the flysheet had a fine film of mildewy dust on it. We wiped the entire inside of the fly-sheet with cloths and clean warm water.
Friends advised it might be a good idea to repeat this.
You can buy tent fabric cleaner, if you consider this to be necessary.
The new owner may wish to re-proof the fly-sheet, to be on the safe side, despite the fact that the tent has only been used for one holiday that I can think of. If it has been used more than that, it will have been only one other time.
I would be happy for people to come and look at the tent before deciding. However, it is a good tent!!
Photos are of the fly-sheet up on the lawn. It was just put up fairly casually, purely to check it out, air it and clean it.
