I guess it's time for empirical evidence, rather than opinion. Below are two pictures, 1970s LePro on the left, and current LePro on the right. As you can see, there is a considerable difference in the way they were made. The earlier ones had an irregularity about them, and the current ones are more smooth, symmetrical. The second picture has the bottoms sanded off. The earlier LePro is recognizably darker, though not black, as some have suggested, but darker.
There are some sensitive types here who like to rant about fake, conspiracy, fraud, or what have you. It's what they do. Those are not valid here, as you can see the earlier LePro is darker than the current, and constructed a bit different. It has nothing to do with age, as I've got older tips that are the same color as they started. This doesn't mean all 70s LePros are darker, as there could be some variation in leather or tanning technique.
Those of you who thought the earlier LePros were darker, you were probably correct. Those of you who thought there is no difference, I would hope your mind is opened a bit. And unfortunately, some will think conspiracy, as that's how their minds work.
Hope this helps.
All the best,
