Those "factory" shots remind me of a certain "grocery store" used to operate in a particular Baltimore neighborhood. Basically every can on every shelf was years past its sell-by date, but in back, along one wall there were 20 or 25 "for amusement only" video poker machines, which yielded a decent living for the owners/operators of this grocery store.
As with the store, so too the Chesil factory, except instead of illegal gamblin' he got illegal gardenin'.
They look about the same on the tax forms at the end of the year.
