Super 2 Bar question

[axehacker]

I recently acquired a well used Super 2 with 10" bar.  I noticed the bar doesn't have a sprocket.  From what I can tell, these did not come with one.  I found a NOS bar on ebay and there is a funky metal guard on the nose of the bar.  Is this necessary?  Mine is missing.  Trying to decide if I can refurb this bar, or if I need to replace it. 

Also, is there a place to order a decent replacement 10" bar that will fit the Super 2?

Those 10" Hard Track bars were not known for longevity. There was also a 12" version. When I was in the shop we typically always tried to steer folks toward a roller tip bar (Power Tip) when replacing a hard track bar. The roller tip would last much longer and didn't rob any power.

The Saf-T-Tip as Homelite called them was utilized on new saws to meet some government anti-kickback standard. I would never advise anyone to remove it, but I will tell you when saws showed up in the shop for repair, there was rarely one with the Saf-T-Tip still installed.
