What is it (Stihl edition)?

[DGersic]

Going through Dad’s stuff, found this with the boxes of lawn mower, trimmer, and leaf blower parts. It says Stihl on it. Doesn’t seem to be a part for either the FSA60 or the FS90, and I haven’t found any other Stihl tools it could go to.

Part of a guard for a string trimmer.

Got it. Thanks.

It goes on the guard that’s on the FA90, not the other guard I found with it in the box.

Aw, and here I thought it was a Stihlatinny rail for mounting optics on a line trimmer....
