So far I have discovered 5 different door hinges. Now, to be 100% period correct we can only try to approach the correct VIN when things have changed. The first hinges were lot thinner and only the very first did have the grease nipple. On doors of body number around 1500 I found the early hinges without any grease nipple. Not sure when the reinforced and chunky hinges were introduced. You are welcome to let me know your hinge type and what VIN you have. Many thanks
