…and this: “The trailer in this thread is employing lenses derived from Lighthouse technology by the Chance Bros Co . The Chance light illuminated the left side of a runway edge as viewed by a landing pilot. The trailer was positioned about 30 ft from the threshold . the 4 leveling jacks on the floodlight unit enabled it to be set up with great accuracy. As an aircraft joined the circuit ATC would instruct the crew manning the light switch it on. Comms was normally by a field telephone arrangement.
As soon as the kite was safely down off went the light. At the end of night flying the Chance light would normally be towed back to the Night Flying equipment shed adjacent to ATC.”

ok, the NY Times pubished an article April 3, 1928:
“Hanns Klemm, designer and builder of small planes, arrived yesterday from Bremen on the North German Lloyd liner Dresden….Three of the Klemm planes, which have a wing spread of forty-three feet and are equipped with a 20-horsepower motor, are already in the country. Kern brought them with him when he arrived several weeks ago. They are to be used for demonstration.”
Two points:
1) Klemm came to the USA April 2nd 1928. (No mention of “five planes” that he brought with him!)
2) Kern imported three planes,
c/n 33, later registered NC4825 (it’s the plane he bought in Germany and which he named “Yankee Doodle”)
c/n 52, later registered NC4922 (it’s the plane that Charles Lindbergh made a test flight with)
c/n 53, later registered NC4921 (it’s the plane with which the thread started!)
Only c/n 33 was registered in Germany (D-919) before shipping to the USA

Boxman – I agree to your last sentence in post #9

The three photos of Klemm, Kern and Seypelt were shot in Stuttgart, showing the L20 D-919 “Yankee Doodle”
The first sentence above the photos translated: “In the autumn of 1927 Hanns Klemm was visited by two Americans , George Kern and Willibald Seypelt who bought each a L20.”
For further research it would be helpful to get the complete file of NC4921 from FAA!

edit 1:
Willibald Seypelt was owner of L20 c/n 53 reg 4921 – certificate canceled December 1st 1928
George Kern was owner of L20 c/n 33 reg 4825 – certificate canceled December 9th 1928

edit 2:
“On October 21, 1927, Albert Willibald Seypelt (d.1966) and George William Kern began a tour of Europe in a lightweight Klemm-Daimler L-20 dubbed the ‘Yankee Doodle.’ Leaving from Stuttgart, Germany, the duo travelled over 6,000 miles visiting Belgium, France, Italy and Austria before returing to Stuttgart on January 20, 1928.”

AERONAUTICS: Air Flivvers
Monday, Mar. 26, 1928
“Having toured 5,000 miles of Europe in his “vest-pocket airplane,” the Yankee Doodle, George Kern Jr., son of a meatpacker, retired, returned to the U. S. last fortnight to show the incredulous an air flivver which weighs only 575 pounds, costs $2,100, flies for three cents a mile, crosses the Alps.
It was as he was flying across Europe in a commercial airliner recently, that Tourist Kern met, as fellow-passenger, Willibald Seypelt, German flier during the War. Enthusiastically, Pilot Seypelt told the U. S. tourist of a tiny plane made in Stuttgart, after the…”http://content.time.com/time/magazine/article/0,9171,787034,00.html
“Tourist Kern, enthusiastic, wrote a check; in two and one-half hours of instruction he became Flier Kern. With Pilot Seypelt they set out over Europe, over nine different countries, 5,000 miles Total expenditures for gas, oil, etc.: $180. In the U. S., where gasoline and oil are cheaper, the cost would have been no more than one cent a mile.”http://www.wordola.com/wusage/seypelt/all.html
