My foggy memory says that the really early packs had brown paper skins, or at least that's what I remember.

Then again, I know enough about memory to know that memory is incredibly unreliable, or at least that's what I recall...

Yes, the original batteries in my HP35 had the brown paper skins.

Actually, even the early 82033A's had a sleeve around the cells. In my case the colour was best describes as mauvish brown -- perhaps magentaish.

The 82001A pack I rebuilt had brown paper around the 3 AA NiCads (450mAh capacity). This was from a 1977 HP67. The only other thing on the battery pack is '1819' heat stamped - is this a sort of date code? (I'd guess it does not mean the year 1819!)
