British Aerial Transport F.K.23 'Bantam'
When the British Aerial Transport Company closed down in 1920,
the 'Bantam' was part of the property bought up by Ogilvy
Aviation, a trader in second hand aircraft and parts. After
Mr. Ogilvy’s death in 1953, the 'Bantam' remains, one cut
up fuselage plus wings of two different 'Bantams', were donated
to the Shuttleworth Collection and stored in a barn for many
years. In 1975 the remains were moved to someone who planned
to restore the 'Bantam', but the material got returned in
1989 without any work done and some vital parts lost.

Around 1990 it was decided that only aeroplanes collected
by Richard Shuttleworth himself would be kept in the Shuttleworth
Collection and the 'Bantam' remains were offered for closed
bids. Thanks to the enthusiast support from the Stichting
Vroege Vogels (Early Birds Foundation), the newly formed
Koolhoven Aeroplanes Foundation was able to make his bid for
this last surviving, original Koolhoven aircraft in the world.
All other interested gentlemen welcomed the thought of this
and withdrew their bids!

April 1991 the remains of the 'Bantam' arrived in hangar
8 at Schiphol Airport and a restoration team was formed:
| |
Herman Beker, constructor and draftsman; |
| |
Arie Groen, aircraft engineer; |
| |
Piet van der Horst, woodwork; |
| |
Lou Kolsteeg, engineering and systems; |
| |
Ton Hulshoff, engine; |
| |
Harry van der Meer, woodwork and project manager; |
| |
and for the Stichting Vroege Vogels Jaap Mesdag, licenced
engineer and pilot. |
| |
Back-up: Ir. Frank van Dalen, aeronautical engineer and chairman
of the Koolhoven Aeroplanes Foundation. |
After a survey of the material, it was decided to take all
parts of one identity and reconstruct it to one original aircraft
for static display. During this process drawings of all parts
were made to document the aircraft in detail, thus enabling
the Stichting Vroege Vogels to build a 'Bantam' in flying
condition.

To have a connection between the 'Bantam' and The Netherlands,
it was decided to finish her as the civil K-123. With this
registry the aircraft was a daily highlight of the E.L.T.A.
in 1919, the first big aviation exhibition in The Netherlands.
K-123 and Koolhoven's private 'Bantam' G-EAJW together, daily
performed aerobatics that thrilled the audience.
July 1918, K-123 was flown to France in order to be tested,
together with two other allied types, against a captured Fokker
D.VII. The 'Bantam' proved to be superior to the D.VII in
two out of three tests.
The 'Bantam' was extremely fast. In those days fighters had
top speeds from 90 to 115 mph ... the 'Bantam' reached 142
mph!

The restoration of the 'Bantam' started with a careful selection
of the aged and corroded material. Three wings appeared to
be in such good shape that they only needed repair.

The fuselage however was cut up in many pieces, yet the front
and tail sections had survived. With an archaeologist approach
it was all succesfully reconstructed and rebuilt upside down,
using the top longeron as datum line.


Most steel parts were badly corroded, as were the aluminum
fillers used all over the place. Without exception steel nails
had been used in the wood, which in 80 years had corroded
to ten times there size; they had to stay in the wood as they
were.
The static 'Bantam' is fitted with the original Wasp engine.
The flying 'Bantam' will need a reliable replacement as the
Wasp was known to be very unreliable because of its poor design
and construction.

A jar with synthetic cassaine glue, almost the same as used
in 1918, was obtained from Guy Black in England. From a received
subsidy flying wires could be bought from Bruntons in Scotland,
the same manufacturer as in 1918.


The restoration has been done the hard way. Wherever possible,
broken parts and pieces of wood were repaired instead of replaced.
Thanks to this meticulous approach, the reconstruction of
the ‘Bantam’ consists of an exceptional high percentage of
original material: 90 to 95%.


August 2003 the B.A.T. F.K.23 'Bantam' from 1917, is restored
to its full glory; twelve and a halve years to turn a 'pile
of firewood' into a beautiful swift looking aircraft. Five
engineers have spent their time to the 'Bantam', along the
way helped by some 20 other people providing skills, knowledge
or parts. These people can look at their work with great satisfaction;
it has become a museum piece of great historical value.

The help of the Stichting
Vroege Vogels, in particular their secretary Jaap Mesdag,
has been crucial for the project. Without them taking care
of the finances, it would not have been possible to bring
the remains of the last existing Koolhoven aircraft to The
Netherlands.
Today the 'Bantam', the last real life example of Koolhoven's
work, is on public display in the main exhibition hall of
the Dutch National Aviation Theme Park Aviodrome,
that also contributed to the project by providing accomodation
and facilities for the restoration.
