Dan Q archived GC54F7J Oxford Steganography #3 – X-Ray

This checkin to GC54F7J Oxford Steganography #3 - X-Ray reflects a geocaching.com log entry. See more of Dan's cache logs.

It’s proved impossible for me to re-create the lenses used as clues in the parts of this series that have been “muggled”, and it seems that the only solution is to dis-assemble and archive the entire series. The bonus cache (#5) will remain available until March 2016 for anybody who’s solved the puzzle but hasn’t yet found it.
