I would like to clarify an important point.
I do not use a portable xrays machine, they are illegal and dangerous.
I have access to real xrays machines, installed by the book and in full safety. I am qualified and licensed to use such equipment and I am experienced in the interpretation of the results.
PLEASE, do not take my posting as a suggestion to take XRAY lightly, THEY WILL KILL YOU, and you neighbor
Some or all of you have special skills and bring them to the fore for us all to enjoy. But not all of us have all the skills in the world. I do not mess with resin composition and chemistry, I do not know enough about that.
Please so not play with x-rays.
I have been a member here for a short while but I have been collecting and restoring pens and other stuff for 45 years. I just did not want to brake this one.
