old monitors

Some of the monitors I have broken down have cowlings inside the plastic molded covers. I am assuming that these are aluminum. Is this correct?

any chance you could post a pic? I don't think i've seen this before, and i've done alot of monitors...

Have not posted pics on this forum before but will try to get a pic and post it. The cowling is the same shape as the plastic shell and is very thin and malleable.
