ID an old homelite trimmer

[Hendersonjk]

I`ll have to take a pic later but has anyone seen a homelite trimmer that has the motor on the bottom, the gaurd is the muffler!, the shaft that connects the handle to the motor is the gast tank. I thought of tearing it apart but it just needs an o ring for the tank. its bad unbalanced for actual yard work . priceless or gas skate board parts?
