I've got quite a few lovely meters with that steel casing, about 22 or so of them through the model ranges of Test Set No 1, 8X, 9SX...

I stand corrected on this. I opened one up yesterday and it's a case over the plastic case it seems.

The metal cased 7's I've opened in the past were simply metal with no plastic at all.
