Please can anyone tell me if they either recognise the manufacturer of the kitchen monobloc (see attached photo 1), or if they know how to remove the cartridge in the second photo and what tools to use. The spindle has a clip around it inside the hexagonal recess, but it is proving difficult to pull out. It looks like the outer ring with the 'hex' hole should be unscrewed and removed first.
Any help would be appreciated as the tap has developed an increasing drip!
