What Kind of Bar Do I have?

[CalebJones]

So, I 'inherited' a bar when I moved into a house about 6 years ago. It's straight and great. However, as I have read more about bearings versus bushings and such, I've gotten curious to know what I have. I've posted a picture, and (obviously) it's a Texas Power Bar Capps, but I was wondering if the end cap would reveal more information about what I have.

Any thoughts from the forum?
