The Sippe Monoplane was a single-seat tractor built at Beckenham, Kent, during 1910 by S. V. and A. H. Sippe and James Jensen, and was tested at Addington, Surrey, towards the end of the year. The fuselage was of welded steel tubing in front with a bamboo tail boom; a four-cylinder air-cooled engine of 20 h.p. - believed to have been a Henderson - was installed.

ANOTHER BRITISH MACHINE.
I enclose two photos of a monoplane, which I hope you will consider worthy of illustration in your journal.
This machine was built by my brother and a friend (both engineers) and possesses several novel features. The frame is made of steel tubing, welded by oxy-acetylene process; the backbone is of bamboo, and the main plane is in one piece, and can easily be detached from the frame.
The pilot's seat is below the main plane, giving a low centre of gravity.
All the controls are by the steering-wheel, which is raised and lowered for elevating and descending, and moved right or left for warping wings.
Although this machine was designed long before the particulars were published in your journal, it is very similar to the successful German monoplane built by Herr Grade.
The constructors have been unable to give this machine a fair trial owing to lack of funds and a suitable practice ground, and I thought you might be able to put them in touch with someone interested who would assist them, for a share in the machine.
