Hi Jeffrey,

thanks for your answer and recollections on the famous hammer test ;-)

There is a youtube video showing some of the testing...

..but the hammer is not hitting the device under test directly, but
it is hitting a big steel plate where the device is mounted to (indeed
simulating a submarine in harsh "conditions")...

Yes, lot of metal inside those Rolms. Although all Aluminium, they 
are veeery heavy and I always wondered how many of them also have
been used in airborne applications, where weight is an issue ;-)

Best wishes,
