Well, those tangential worm-screw hose clamps have an
impeccablegenealogy. They were invented in Britain in 1923 by the I.
Robinson Company under the "Jubilee" name. The first customer was
Rolls-Royce, so you know the originals were well-made.
In the U.S. we were still using more pedestrian hose clamps, of
which the Witteck Company's "Noc-Out" brand was the best-known, in
factWittek sponsoredIndianapolis racing cars known as the "Noc-Out Hose
Clamp Specials" between 1940 and 1947.
Floyd Davis and Mauri Rose co-drove the winning car in 1941 as the
"Noc-Out Hose Clamp Special,"
But the "Jubilee" hose clamp came to the U.S,in 1943 as equipment
on the Rolls-Royce designed water-cooled Merlin V-12 aircraft engine
used in the P-51 Mustang fighter. Packard built Merlins here under
license and had to have such hose clamps made inthe U.S. They were
Race car builder Frank Kurtis adopted the Jubilee clamps after WWII
because millions were available in surplus from North American Aviation,
I suspect that mil-spec (aircraft quality) clamps will do pretty well on
