    Aye. The "physics" say HP X .746 for KVA, ergo 5 HP is only 3.73 KA.

    They are made for easy lift-off, no tools required.

    Note from Peter's photos the pair of "U" shaped slots.

    Oh, they would have not only been "stock items", but also choices that had enough OEM use that they were expected to remain so and in the supply-chain for years.

    In line with Hendeyman's first-owner history + a bit of Google-fu, note that said firm operated (at least...) out of Teterboro, NJ, so it may have been moved but once.

    Post 2 covered it.

    The Royal is faster to change (and simpler) than ANY of the alternatives that I have here are.
