Hi again folks,

It has been a while, but,

correct me if I am wrong,

I remember cutting up a few Henbury Irons and polishing and etching them, a
few that I left in my etchant for way to long ended up looking very much
like these pics.

Is an "over etch" the standard way to get these Neumann lines to become
visible?

Cheers, Kevin Forbes, VK3UKF.
