I have three of these tubes, but one of them is totally
The first one is dated '1 FEB 87' and is the old traditional
construction where you can see a spiral seam all the way round the
tube from one end to the other, and the design is in a matt
However, I have another one that looks almost exactly the
same but is of a new construction, where the seam runs in a straight
line and the design is in a gloss finish.The
best before date is also stamped into the base, rather than printed
onto it. This is the way that all future tubes would look. The best before date is
exactly the same though, '1 FEB 87'.
Here's a thing though. I have a third tube that is of the old
construction, but the best before date is ''1 APR 87', two months
after the new style tubes went into production. There are a few
possible reasons for this, the most likely being a change over
period between the machines that made the tubes. It is a bit of an
interesting quirk though.
