Gunwolf,

thank you very much for the scan! It is interesting, however, that Westley Richards with drop locks doesn'g seem to have become the weapon of choice for safarists. Whatever the advantage of quick detacheable locks, the people who actually were going out there didn't seem to care. I can't boast of reading absolutely all pre-WWI safari books, but I've read a lot. The only Westley RIchards mentioned that I remember was Alfred Neumann's .577 express, which had a single trigger which broke down. Incidentally, this is one of the very few double rifle failures that I remember reading about.

This returns us to one of the original questions - how common were gun breaking down with British sportsmen on the turn of the XIX and XX centuries?
