1874e Petros Rifle
1874e Petros Rifle is worth keeping when you want careful 11x54 mm shots or a base rifle for the later Petros upgrade path; panic fights punish it fast.
EB Revolver is the 8x21mm revolver family page, useful when you are deciding whether the Zseb or Bantam path fits your sidearm slot at all.
EB Revolver makes the most sense as a family choice, not as one mystery gun. The EB line is a slow 8x21mm six-shooter with two familiar branches: Zseb and Bantam. So the useful question here is simple: do you want to stay on the cheap EB revolver track for a while, or are those ammo and parts better spent jumping to something stronger?
The EB Revolver family is found on Sophie as player-weapon loot, with Zseb and Bantam serving as its common and upgraded forms.

1874s Petros Sniper Rifle is worth the slot when the run really gives you range and enough 11x54 mm ammo to cash in on it; cramped fights expose the risk fast.
866/9 Rifle feels like the sensible early rifle when the run expects medium-range fights and already has 9x42mm ammo behind it.
Anti-Reactor Rifle feels worth the slot in runs that actually want to pressure Trampler systems before boarding starts.
AV1 Rocket Launcher feels worth packing when you already have Rockets and expect targets that are worth burning them on.
Black Box only starts to matter once you have already won the reactor fight and still have enough left to get home.
Blitz 10R Pistol feels like the middle-ground Blitz: enough magazine to be usable, not enough to pretend it solves every close fight.
Blitz 15R Pistol feels like the Blitz version you keep when you want the family at its most forgiving.
The EB line makes sense when you want a simple revolver backup and do not need to spend immediately into a different gun family.
Its weakness is not mystery; it is commitment. If the route wants longer reach or heavier burst, staying on EB ammo and EB upgrades can be the wrong spend.
