2002 Hoffman EP

EP

I think this is the last year of the Ep.
Upon close examination, I've found several
key differences between my 2000 &
2002 model EPs frames: 
                                            1. those frame-stander bars
                                     2. My 2000 EP star has a coaster brake bracket welded on (how weird!)
                             3. The overall size of the rear dropouts has been cut down to save weight.
                      4. Also, the 2000 model features two sets of rear brake mounts, giving you two possible places you can put them. (upper and lower)
 
 
I'm curious if anybody knows how to tell if this is a Star or Pro frame ?
There must be some way to look it up with the serial no. ?
