I believe (not old enough to remember) they are an old school tool, that are still valuable. When I was a kid, I notice most of my grandfathers stuff, came with breaker bars, they no longer do, but instead come with ratchets. Maybe someone with some of the old catalogs, can share the price of the adapters in them, with the early ratchets. Breaker bars extend ratchets lifetimes, these allowed you to carry less.
