Underhammer lock designs/diagrams?

[Wudsruner]

Does anyone have any diagrams or models of an underhammer lock? I am working on a cheap squirrel blaster and I want to design as simple a lock as possible completely homemade. From what I've read, the underhammer is an easy lock to make with few moving parts. Also, I have little experience in lock making, the only working lock I've made being a copy of a poachers gun (which was definitely not a standard lock )
