Team-work?

       Yup.  One of the Team worked, the other watched, and passed/found Tools.
      Doesn't time fly when you blink?  I had NO idea it hadn't been mucked out for two Years, but two nests were extracted, along with one wee crawly-beastie.
      I had a screw in the side, it had rusted almost beyond recognition - a rusty, threaded, Spike with no head at all. Damthing was only in about 2-3mm - BUT - enough that it was necessary to actually beat the top off THEN remove the 2-3mm so the Lid would re-close.
      The extra? ALL the tools which were eventually used; some his, some mine and YES, even the stick and the Trowel. One section of nest, maybe even older than the previous two that I'd missed even more years ago needed the Trowel as a Crowbar; just the correct width to fit the Box and strong enough to lever out the Dross.
