GE A-66 new refurbish job

[de.facto7]

Fantastic!

.. a couple very general but necessary questions before I start this project...

Are there any abnormally toxic materials that could be found in parts of this period?

Are there any bad combinations of chemicals that I should avoid either that could be hazardous or could cause damage to these wonderful ancient artifacts?

and.. is there anything that is delicate that I should just leave completely alone?

Thanks again...
