Not like a 6040A key used with single line phone, because the 6040A has  the T and R for each line extended to the 6040A, just as the 564, 464, etc. It's more like a 462 set, 466, or 566.

Rather, there is a common talk path, regardless of which line you are on. The 750A switches each phone to the appropriate line (1, 2, or 3) or dial selective intercom (L).

Makes me fantasize about the rare treasures buried away at ex-bell employees houses and basements...It's out there, and this one will be too! One day leaving the hands of it's collector, to be passed onto someone like you and I...
