Hello,
What means "THORN" on these fins (original ww2 US HE 81mm M43A1) ?
Is it an US maker ?

Sebastian, even with my computer set on "Blurr" I can't read it.

Most likely the manufacturer.
 
I can't find THORN in MIL-HDBK-1461A "AMMUNITION MANUFACTURERS AND THEIR SYMBOLS" 1998, and MIL-STD-1461E "AMMUNITION MANUFACTURERS AND THEIR SYMBOLS", 1990
