This is my second Hawthorne 60 6439, this one is a Johnson 710A. The first one I bought is a Johnson 710B. The main difference is the 710A has a rear bearing for the drive shaft. The 710A also has a set screw for the push button to turn on, the 710B has a pin pressed in. The only other difference in these two reels is the copper colored front cap on the 710A is faded.
