According to the homeowner, her metal hurricane panels are at least 14 years old. The only etching/stamp I found was one with three letters, “AMP” (see photo). Any idea who the manufacturer might be? Thanks!
Can’t find anything on AMP. If that’s all you have to go on, then default to N1 and let the client produce the information needed.
That looks good Tom. Michael Please let us know if you get the info.
