If you're still looking for this schematic, please contact myself or LadyReyven. We have one we'd be willing to trade.
Optimally, we'd prefer the SafetyDance book. Alternatively, a negotiable amount of lead ore would be acceptable.
Let us know when & where to meet. We live in the NE quadrant, so any place in that direction would be reasonable for us to travel to.
If you'd prefer to set up a dead drop, PM me with co-ords and a passcode for the container.
