Browsing the Warhammer 40,000 Compendium from 1991, I noticed few printing errors at page 12. While the statistics line of the basic Traitor Terminator marine has shifted one column too much at the left, how about the equipment options and their point values?
Standard equipment is given as follows:
Sergeant: Storm Bolter, Power Sword
3 Marines: Storm Bolter, Power Glove
1 Marine: Storm Bolter, Chain Fist
Options
Replace "Chainfist (one marine per squad)" with "Heavy Flamer" at cost "Nothing"
Replace "Chainfist (one marine per squad)" with "Assault Cannon" at cost "Nothing"
Replace "Power Sword (Sergeant)" with "Chainfist" at cost "20"
Replace "Power Glove (all so equipped)" with "Chainfist" at cost "50"
The drawn unit illustration shows the standard equipment only, so it's of no use. Lost and the Damned by comparison allows the Nurgle and Tzeentch traitor Terminators to choose freely between power gloves and chainfists with no point difference, and list both assault cannon and heavy flamer as replacement options for storm bolters at 50 points each. Compendium has with the Imperial Terminators heavy flamer and assault cannon interchangeable with each other with no point cost difference, as is also the case with the power gloves and chain fists.
So, should the correct traitor terminator options be then:
Replace "Storm Bolter (one marine per squad)" with "Heavy Flamer" at cost "50"
Replace "Storm Bolter (one marine per squad)" with "Assault Cannon" at cost "50"
Replace "Power Sword (Sergeant)" with "Chainfist" at cost "Nothing"
Replace "Power Glove (all so equipped)" with "Chainfist" at cost "Nothing"
