Hi Andrew,
I was certain I was running the latest version, but just to be sure I
grabbed the latest version.
Same result, same offsets.
I can make the sample available, but more than happy to do whatever
debugging needs doing (if I can!)

Are you using the latest git checkout of Volatility or
the 2.4 release?
Can you try the latest checkout and re-run Volatility strings (you can
run it on just the offsets from PID 123 to make it faster).
If you are already on the latest checkout then we will need to debug
further.
Thanks,

Nope, still no banner. But it is identical to what I find at 0x1a34d8 in
123.dmp. (As you'd expect.)
Double-checked that I was searching Unicode and ASCII - still no luck.
Hmmm.

Can do you:
vol.py ... volshell -p 123
Then in volshell do:
db(0x75b6b4d8)
And see if you get the banner printed at the beginning?
Also, how are you searching 123.dmp? Did you search ascii & unicode
(most common error)
Thanks,

Writing
myapp.exe [ 123] to 123.dmp
However, if I search 123.dmp neither the BEGIN or END strings are
present.
So I thought I'd try and find it via the virtual address give,
0x75b6b4d8:
