About 10 years ago, while we were in Italy, one hinge of a cabinet broken. I looked around every hardware workshop and was not able to get a replacement. I finally discover that they should be of the brand BLUM and that the exact reference number should be know as there are hundred of pages in the Blum catalogue. The 3-cabin, 2-bathroom Oceanis 40 uses 34 hinges and their corresponding 34 mounting plates. In the following pictures you see the reference numbers and the quantities used in the Oceanis 40. 

I was able to get replacements here in Portugal at a Blum distributor, recently. Some of the replacements were not available or were obsolete and I got the parts shown below which are fully compatible with the referenced to parts (the above numbers were taken from the existing parts in 2015 and the boat was new in 2010). I see that most of these parts are available in web (Amazon, Ebay, etc).
