Like John I have a couple of the older irons. I had three of them, one was given to me and the two I have now were bought at a club auction, found in the button of junk boxes. It's how I got my incidence meters too. All of the irons on the market are pretty good so it's just a choice thing, more like price. I need a tough iron too, I tend to drop them a lot.
If anyone has a spare flat shoe for a trin iron I'm in need!! I keep looking in box bottoms and corners at swap meets but haven't found one yet. I should buy a new trim iron, mine is held together with tape and hose clamps but it has been with me for a lot of decades.
When my one iron decided to burn out it tried to burn my building board and shop down. Don't leave your iron on when you go in for lunch!!!!!!!!![X(]
Things that dumbass married to my wife does!
