Today while unpacking some more stuff after the move I found the pan from my
grandmother's kitchen scales (it was packed in with books and cables, go figure..)
Anyway that meant I could weigh a DECtape. The reel in the plastic case weights about
6.75 ounces, the reel on its own (with the tape on it, of course) weighs about 3.8 ounces.

So your guess was pretty good. Certainly near enough for this

Said scales are of the sliding weight type so there are no springs that could have gone
soft over the years. Yes, corrosion probably has affected the weights a bit, but not enough
to worry about.
