DIY forged Touch Mark out of an old car spring

[Philip Davies]

Sehr gut! Herzlichen willkommen!
Can anybody confirm the tradition that a mark must be PROVED? I believe this was so among the masons, and perhaps in other guilds. By proved, I mean either that the mark was approved by masters when the apprentice or journeyman had reached a required standard, or that it was geometrically proven, in that it was based on a construction of straightedge and compasses.
