The cranked hinges for cupboards used extensively on the Classic Series are made by Pinet (in France) https://www.pinet-industrie.com/en/products/1474-small-butt-hinges-with-one-cranked-leaf-38-mm part no. 60-1-3525. Whilst still available on the Pinet site they are nonetheless difficult to get hold of. I purchased replacements 14 years ago, and had to buy a MoQ of 10. The supplier (in the UK) no longer stocks them.
