Arrived from supplier with slight damage. After sending us a replacement they didn't want the old one back! It's this sink
https://www.rangemaster.co.uk/products/rangemaster-stainless-sinks/oakland/755 which retails for around £300-£350.
PLEASE NOTE it's not reversible and the drainer MUST be on the left side. There is very slight scuffing to one corner (see photo) - would probably polish out with some cream cleaner or other very fine abrasive. The foam rubber sealant strip is somewhat damaged and you would probably want to replace it. Comes with a full set of waste fittings and mounting clips, but NO TAP. Has just one 35mm tap hole suitable for a mixer tap.
