Thanks Tom! I read your article earlier, but your Stover WI has different handles. The one I just threw in the LB has metal coil handles. Before Picks are attached. The close-up is just a zoomed in screenshot of one of the others.
The wire handles seem to sort of screw onto or fit around the outside of WI paddle. It also seems like the rods through the middle of the grips function to hold them in place. Neither would loosen by twisting with the amount of force I was willing to apply. The current plan is to soak the WI in the LB for a while, then apply penetrating oil, and see what happens.
Other suggestions encouraged. I am a little concerned that either the LB, the electro, or the oven could cause damage (discoloration in the case of the oven).
