I know that you also know, but there is something else I would also like to know!

Corrosion of metal stampers seems to be a common problem. Presumably, if incorrectly stored the metal was prone to corrosion from moisture in the atmosphere, and I would guess that over the years this could lead to serious damage. About half of the English Decca vinyl or polystyrene pressings I have contain surface defects due to corrosion of metal stampers, which were made in the late 1920s and early 1930s. Thankfully, the metal survived long enough to be pressed up, despite the damage.
One other point, one which I think has been asked on this forum before. There are very few alternate takes of the Whiteman Columbia sides. Is this because Columbia destroyed their metal fairly quickly while Victor/RCA hung onto theirs?
