✅ SOLVED Printing block or Stamp; Colonial type script on stamp side:

[valleyglen]

This bar like object is copper with engraved script on one side, the other narrow side has
two round iron spots were it appears rods were once part of the whole piece.
Is it a printing bar of some kind to mark leather or paper?

It says brand on it, but can't make out the other letters.

Are you sure it isn't lead. It looks like a lead smelting bar.

lead dosen't turn green, it turns white or a grayish color, Thanks for looking...

I work with printing type in a museum setting with lots of old type, lead and wooden, and it does not resemble anything that I have seen.
The only thing in common with printing type that it has is that the letters are reversed. I would suggest that maybe it is a 'branding iron' of some type
meant to be heated up and then when applied to wood, it would burn the words on it into the wood so that it would be able to read correctly. This would explain the iron attachment you allude to. Many woodworkers would mark their work in this way, as well as boxes, barrels, etc. My guess is that it is a mangled branding iron (made of copper)

Yes a mangled branding stamp of some sort. Thanks for the info, Glen.

While researching something else, I found an article on lead ingots and bars from shipwrecks and thought you might be interested in seeing the color variations.
