Harm, I cannot remember if I talked to you, or a collegue of you at the museum. Can you provide me with a photo of the stamp? I am currently on a military exercise, but will forward the picture to a friend of mine who can most likely tell you what the stamp means. I have the feeling it is an inspection stamp, but if it is specific to a certain factory, then we can maybe narrow down the likely airframes. Danny
