Seeing David's snap cape in another thread reminded to ask this question to snap cape owners... I noticed a while back that mine have the number '5' appearing two times on the female part of the stud. Do others have this number?
Hard to get pics but in hand it's definitely a '5'. On my other cape it's less defined and looks more like an 'S'.
Here's another number '5', pic from JonnyU
