Back in the day, Black and Decker built some outstanding power tools, and not coffee makers and plastic disposable junk tools.

I have for sale one B & D Model 6138 - $ 120 including shipping. Item is used but runs very smoothly, a very stout tool. Buffer is very powerful and will spin a 9" bonnet easily. One of the gear case bosses is missing, which leads me to believe the tool took a hit (floor?), but it is superficial damage.

It has a variable speed trigger and a rotary speed setting dial. The T handle will fit in the right or left side. It appears that this tool has been re-branded as DeWALT DW849 TYPE 1.
