I believe I've seen larger versions of the McLux tail around the top of portable propane tanks used for gas barbeque grills. I think most of these have less variation in the size of the holes, however.
I doubt if you'll find other flashlights with a similar feature, however.
Are you asking if the kroll guard can be fitted to another flashlight? If so, the answer is no, because it isn't a detachable piece - the tailswitch guard and battery tube are a single piece of metal.
And the Kroll won't fit on the top of a portable propane tank either! /ubbthreads/images/graemlins/grin.gif...sorry, long day at work - couldn't resist!
