I'm going to see a MB -that I think is a 145- that being sold for close to $200. I've been trying to compare the image provided by the seller with others than I"ve seen on several websites including this, but they're few and far between. I notice on the photo that the tines are far wider than the plastic feeder on the image but all pictures that I've seen of the 146 and 149 undersides align perfectly. Any idea as to why is this? Could this be a fake pen? The owner is offering the pen with its original box, what should I look for in the box for an original item? What kind of papers do I expect to find? This will be my first MB if I decide to buy. http://img.segundamano.mx/images/07/0707278620.jpg
