More of the same.
All the instruction text is exactly the same, complete with the same example as Set 1 – ie they didn’t bother updating it with an example from Set 2.
As with Set One, the copyright information was registered 5 years later, and looking at periodicals of the time paints a very different picture.
Judges Guild Journal issue N, August/September, does not list this. Then Judges Guild accessory O, November, does list it as “NEW”.
White Dwarf issue 3, October/November, does not list it. Issue 4, December 1977/January 1978 finally lists it. Of course, the UK is always behind.
What’s clear is that February is way off. I think around September is more likely.
