WW2 Tank Suit

[Flying10uk]

Possibly there was a lightweight version for use in hot climates?

Interestingly, I have heard of people using surplus ex-British army tank suits for motorcycle use some time after the Royal Tank Corps had started using black cover-suits.

Any ideas on what looks like a series of pen holders on the left breast pocket, 2nd picture on the bottom row, Jim? I assume that they aren't actually for a row of pens/pencils. Another suggestion, years ago, was holders for rifle/pistol ammunition which also doesn't seem likely.
