L. B. Industries is a carousel in The Blind Helmsman, released with Mr Chimes' Grand Clearing-Out. It is a variable-length grind, and uses Foreman's Favour as a progress quality. Each point of Foreman's Favour has an assumed value of 0.1 Echoes, as well as a bonus of 1.5 E for turning them in. Turning in your points takes 3 additional actions on top of the actions spent gaining Foreman's Favour. Any surplus points of Foreman's Favour you may have are exchanged for a secondary reward. The activity uses all the main attributes.

The carousel is notable for being a good source of Ratty Reliquary as well as one of very few sources of Fourth-City Echoes and Crackling Devices. Both can be spent in The Rat Market, and the latter also has some high level uses (though has better sources once players reach that point).

Ratterbox serves as a randomizer, similar to The Airs of London.

If you leave without cashing out, you can re-enter and leave without spending actions on it.
