Thank you for bringing this to our attention. As Taily has mentioned it appears to be this latest batch. We are now having to rework all stock and replace existing stock. If Vombil sends me his address I will send a replacement one immediately. The material is top quality and not the issue as the first few batches were fully tested, approved and supplied. For a part like this there are not many companies prepared to invest in making it, let alone companies wanting to make small quantity runs. comparison.jpg
