Bummer. Been back in touch with the Bloke in the Union Offices

The offices have been gutted. The main Meeting Chamber is not recognisable anymore.
He told me there's nothing worth photo'ing unless I wanted a photo of a modern day office or kitchen.
When the NUM sold the offices, the house was sold as a seperate building.
The passage way between them was bricked and sealed up.
If I wanted to get photo's of the interior I'd have to contact the current owner.
The house is up for sale at present, so I doubt the owner or estate agents will put themselves out
to meet me and allow me access to it
Oh well, never mind, though I may try contacting the owner,
apparently he has a business in chessy of which I have details.
