another image, does not have the "ALC24ST". I can see "ALCLAD" on it but that is all I can make out. this was said to come from boeing circa 1939.

Nice finds, Kevin.

Could you go back and add urls to your pictures for reference?

Your second photo seems to have ALCLAD (upside down from our point of view) followed by a number series I can't quite make out.

I suspect your third photo is WW2 era--we've got Rosie-the-Riveter types and it's a color photo...

the URLS are nothing specific, most things I found by just using Google. The P-35 image came from a gentleman who is building one from scratch. The B17F I honestly dont remember... while the last one was a human/women's rights article so who knows what the real year was.

Another interesting thing about the pictures Kevin posted is simply that they show manufacturers other than Lockheed installing skin with labelling "out"

From Ric much earlier in this thread:

..which was consistent with standard Lockheed practice.  The attached photo shows an Electra being built with the labeling on the exterior side of the sheet.  Other manufacturers such as Boeing and Douglas seem to have put the label-side on the interior.  It may be that the presence of the labeling on the exterior side of the artifact is another indication that it came to Nikumaroro via Burbank.

A search with Google Images indicates this photos was taken at Douglas Aircraft, Long Beach, in 1942.

The web site Doug Ledlie posted to has a picture showing an example of WW2 era ALCLAD with serif font--bomb rack supports from B-24J-155-CO-44-40332. So Alclad was still being printed with serif typeface during WW2 and here we see it on a type that crashed at Canton.

Did I maybe read something on this thread about which Alcoa plants supplied sheeting to which aircraft plants?  That might perhaps be useful in understanding the Alclad markings...

Good find Steve

Delete specification AN-A-13 and substitute QQ-A-362

AN-A-13 was a specification which was replaced in 1951. Doesn't say when it was introduced but, keep looking.

Here's an interesting shot of what I take to be a B-24 (variant unknown) waist gunner position that shows, at least to me, different fonts within the same photo.  I assume this photo to be in context with others in the series ie apparently archival shots of a fresh airframe, so no repair skin.

Great find. 

I found some WW2 Reynolds Aluminum, first time I've seen Reynolds marking:

Alclad labeling on the B-24 "Lady be Good" can be seen in this on-line photo book.  See pages 12, 13 and 19.

[The photos were taken in 1990-1991 when the wreck was still at the crash site.  In 1994 the wreck was recovered and is now stored at an Libyan air base.  One engine and other parts are on display at the USAFM in Dayton. ]

Great references. Thanks Mark!

[Jeff Victor Hayden]

Mark, I would hazard a guess that the B-24 'Lady Be Good' has been subject to quite a lot of sandblasting sat there in the Libyan desert since WW II and yet the Alclad markings are still clearly visible even where the paint has been worn away.
