I have a '70s 45rpm single by a rock group called Gun Shy. The deadwax
markings by the engineer are more detailed than on any other single I've
seen. Some are hard to make out but this is my best guess, all hand-etched:
+5 EQ STD
BDH1 +1 TO /2
M/W MAC/W +3
Seems to be about the same on both sides except for the 6 digit number
after Musicol. Would these kinds of notes imply this is a test pressing?
