was a producer of diving helmets and equipment from Kiel in Germany.
He started production of the 3 bolt Denayrouze pattern in 1890. The first
style of helmets was the regulator type and this style was in use by the
German Navy until around 1908.
The free flow style became more popular and many of the regulator helmets
were converted to free flow from then on. Flohr developed a unique quick
release system to jettison the divers weights in an emergency as seen below.
A good example of a Flohr 3 bolt helmet.

On the rear photo below the neck rings and the central bolt you can
see the hook on which the regulator was hung. The addition of a hook
however does not always
signify that the helmet was a regulator helmet as some free flow
helmets also had hooks. We can only assume that the patterns were
not changed when the style of bonnet changed.
On the right hang photo we can see a blanking cover. This is the
point at which the backpack was one connected to the hose, revealing
this was once a regulator helmet.
