[Boatanchors] Help needed for locating aluminum box project stock - Lancaine?

[Greg Mijal]

Does anyone know  where I can find sheets of thin, easly bent  aluminum with lots of prepunched  small and large holes in it.  This stuff was used years ago for making cabinets for ham projects and is very easy to work with.  I thought it was called Lancaine but googling that comes up with nothing.
The 60's, 70's and 80's ARRL handbooks are loaded with projects using this stuff.
Thanks!
