Help on doing text effect

[lunymarcus]

Recreating a logo a friend of mine made many years ago.  Don't know how to get a hold of my friend anymore.
As you can see, I got almost perfect match of font, outline and shadow.  But I can't figure out how to do the LF background.
I'm a graphic noob, so I'm actually impressed with myself that I got this far on my own.
Any help or suggestions be appreciated.
TIA

* Create the L and F on separate text layers (the positions are unimportant at that point)
* Extract the path of each layer (Layer > Text to path)
* Hide the text layers
* In the Paths list make the F and L paths visible
* Select the F path in the Paths list
* Use the Flip tool in Transform: Path mode (top row of icons in the options) to flip the path horizontally
* Use the Move tool in Transform: Path mode to move the two paths where needed. Maybe use a guide to have they perfectly aligned
* You can merge them into a single path using Merge visible paths
* Edit > Stroke path on a new layer, and insert that layer in the stack.

I did do a load of screenshots but Ofnuts describes the procedure anyway.
I start from the bottom - the grey background and work up-over. The drop shadow is default Gimp. There is a brighter spot just under the flipped F - I used the dodge tool for that 50 % opacity fuzzy brush, one click.  FWIW the Gimp 3 xcf attached.
