John Ross-
Inasmuch as the movie was made in Kenya, Stembridge may not have supplied the guns. It's always interesting to see what crops up in movies made abroad.
Some odd items were in the best known film version of, "King Solomon's Mines", the one from about 1950, with Stewart Granger and Deborah Kerr (?).
On the "Lost World" TV show (as distinct from the several movies based on the same book by Doyle), the props department couldn't even seem to supply the same guns for each character. They varied some with the season, sometimes even within the SAME EPISODE, scenes not necessarily being shot on the same day.
Rachel Blakely, as Marguerite, is supposed to carry a S&W New Departure Safety Hammerless .38, but at least once, they substituted an Iver Johnson. One character (he kidnapped Veronica, the jungle blonde in the episode, "Trophies") had a Ruger Blackhawk! Pretty neat trick for a show set in 1920! Professor Challenger uses a Colt SAA .45, but the barrel length has varied. Perhaps he took more than one. Lord John Roxton wears either a Colt M1911 .45 or a brace of nickled Webleys with ivory (?) butts, in shoulder holsters. Some Webley Mk. IV .38's have crept in, probably because .455's were unavailable, even in Australia, where the series was filmed. (We're about to give up on a fourth season. Even the executive writers now say that unless something happens in the next few months, financing probably won't materialize.)
In that case and in Kenya, local gun rental houses probably have limited stock, especially with the recent nasty Aussie gun laws.
Oh: Roxton has carried several rifles. I especially like what may be a Sako Safari Grade and one that may be a custom sporter on a Remington M30S action. The safety gave it away...
