How come there are 8? The lock only has 7 pins.
Also which is pin 1 and which direction do they number?
I just assigned a start and direction randomly on my photo

Or, if you
prefer, I can dig through some old posts on this list, and tell
you the depths of the cuts for XX2247. It has been widely discussed a few
years back.

How do you derive those? 2 x "5" and 3 x "7" but there are no such
repeats in the measurements.
Given the "5-1-7-3-7-5-7", a locksmith with a tubular "code cutter"
can
make a key. Most tubular key machines can be used to "code-cut"
But, YES, a prior owner might have removed the lock at some point, and
deliberately rekeyed it to different cuts than it came from DEC with.
Not likely, but possible, particularly in some college CS departments,
where lots of students have XX2247 keys.
They'd have to have removed the securing pin somehow, and that has never happened to
these locks.
