Did you not read my post? I admit it's a bit long but I explained it there.
The short answer is yes. This one is nearly 40 years old.

As juiceme says, you can still get them all over the place, albeit the arrangement is a bit different. The leads are vertical for some mysterious reason rather than horizontal. For example, like this:



Juiceme is also correct that they are not great for fine work. Not only because the tip is too thick for details, but also because it is heated by pushing a big alternating current (in the region of 100A or even more, at a very low voltage) through the tip, which creates a strong, oscillating magnetic field. Good for demagnetizing stuff but can induce current in surrounding surfaces. You can literally feel the effect when soldering large copper plates. The induced current creates an opposite magnetic field that pushes the tip away
