  Approximately 85mm tall

    That suggests that the lamination is around the size of a Dynaco ST-70 output (EI112)
    
    In order to get the numbers quoted it need about 28,000 turns of #38 wire. The part looks original WE, do you have any idea what it was used in?

      My first impression is that the calculations looks reasonable and it is not very hard to do.
      But what a waste of time to make such a choke. Just try a better schematic instead of old EI laminations and a lot, a lot of windings with after all not a very good choke.

        If it were not a Western Electric part, I would question its design, but since WE had the skill and resources to make whatever they need I am curious as to what its original use was.

        If i am correct, its not a Western Electric choke, just the lams are WE.

        The choke pictured above has the Western Electric logo on it. Laminations are bare until stacked varnished and painted at which point any logo can be added. I find it hard to believe that WE would let their logo go on anything that was not 100% their creation. Try putting a WE logo on an amplifier that uses WE 300B tubes and see how quickly the letter from the lawyer comes.

        Maybe the photo was taken before it was rewind but the topic starter say "I'm recently came across a plate choke that is wound with Western Electric WE1048 lamination (Used lams)".
        
        Anyway, if you calculated about 28000 turns even WE is limited with physic laws.

    That's big! I take back my comment; the specs are not unreasonable. I'll edit my post.
