A close look at your dial has me thinking Center Mfg. - their C-100 lock.
And your graphs support this... it's talking like one. This can actually be
a rather tricky lock. The first one I ever ran into really had me stymied.
The wheels are plastic. The process to make them - stamping/pressing
them out - will often leave a bit of flashing on the outer edge of them.
This is likely what's produced that mountain within your graphs of w2.
The highs usually span somewhere around 6-10 incs wide. The gate
will
very often, but
not always(!), be directly across from the high,
or in that general vicinity. i.e. approx 50 incs. from the high area.
For example; IF your dialing sequences have been correct,
w2 has a high from roughly
62-72. This suggests its' gate
will lie somewhere between
12 & 22.
However, you've already established a rather clear gate signature
@ 21 and tagged it to w3. This could mean any number of things;
Wheels 3&2 could be set to the same #, or maybe their #'s are just
relatively close to each other. Also possible that you've mis-tagged
21 to w3... and it actually belongs to w2.
At any rate, there's a number of things yet to explore here, and
a number of ways to go about it. But hopefully this info will help
direct your efforts. Btw, great work! Way to stick with it!
