1. This looks like South Wales but where?
Now identified as Llyn Colliery, Nantyglo SO189109

2. Now identified as Blaenant Colliery near Aberdare.

3. This is possibly in the north-east of England. Doesn't look like a colliery. Any ideas?

4. Consett 'A' Type No.1 (Kitson 1843 of 1872) at a colliery. Consett Iron Co wagons.
It has been suggested with some confidence that this is Crookhall Colliery, Victory Pit
