Lions Harrington pickup

Found this one for $12 so couldn't pass it up. My first made in El Salvador jersey and from what I can tell it was from the 2002 year. I do notice it runs smaller than my Raiders authentics its roughly the same as a 48 in my Raiders in length and width, anyone else notice differences in team jersey sizes like this? Or is the fact that this is an El Salvador made one and my other ones arent? Anyways heres a couple of pics:

pics dont work for me.... but you will notice different teams fit differently. I wear a 52/54 in most teams, but the Bills jerseys (at least from the mid 2000's) have small sleeves and are cut smaller, and a 56 would be most comfortable for me. the raiders tend to fit larger in my opinion as well.
