Thanks! Yeah: I’m sure they can be found if one looks hard enough though. Yeah: moreso in that the datasheet says “Edwards” & “EST” everywhere even though the bell itself is branded “General Signal”.
Oh, really? Huh, okay. Surprised Edwards still sells them since all the photos of the MB6-24 I can find online feature the older label design, implying that they discontinued it some years back, possibly in favor of their own 439D-series (honestly don’t know why Edwards rebranded a supposedly-Amseco motor bell in the first place anyway, unless they wanted to offer installers a lower amp draw bell).
