In fact, some manufacturers indicate really very strange serial numbers that are difficult to understand the first time. I have repeatedly encountered this and it is really a very difficult case, especially if this thing was released quite a long time ago. I was looking for a serial number that had the number 4444, unfortunately I didn't find what I was looking for, but I accidentally found a site. So I discovered numerology. Yes, it's just a hobby, but it's a great way to pass the time!
