I am sorry, but I disagree. You polish to produce mirrored surfaces. You etch/burnish or whatever to produce cameo. To my mind, cameo and mirrored surfaces are diametric opposites.
You are certainly entitled to your opinion, but words can carry slightly different definitions based on the context. Here is one that I think is fitting:
Yes, but I don't see a conflict or problem. It is much easier to polish the fields (i.e. flatter surfaces) than the devices, and a crude job was done on the latter but not the former. That would explain the lines on the devices and the cameo contrasts. I don't see the problem. And here is the full quote:
While I enjoyed the read, this is the only excerpt that is really necessary to prove your point. It is my sincere hope that Doug does not claim to know more about this subject than Tomaska and simply does the right thing here. I am fully expecting a "stand corrected" from him in the near future.
For the record, the predecessor to the Tomaska book was: "Cameo Proofs, 1950-1964 by Val J. Webb". Not an easy book to find but I did a quick search and found two copies, one was less than $11. I'm jealous because I paid a lot more for my copy!
