Thanks DZ. Hope you like this one. Iím psyching myself up to start a project that will leave me with spare wings from the Emhar Anasal. Thinking cap on while I ratched through the spares and re-discovered a discarded scratch built fuselage. Itís got to be forty years old and was my first attempt at scratch building using card. It was supposed to be a Rumpler CIV and the plans came from Scale Models circa mid seventies. While the basic shape was ok it ended up too wide and has remained unwanted for all these years. However, itís not a bad fit for the Anasal wings and I have various bits and pieces from recent projects that Iíd prefer to use and not store for years on end. Hereís the back story.

In common with most countries during WW1 Russia had several main aircraft producers. From Leningrad were Russian Baltic(RBVZ), Lebedev and Schetinin, the DUX conglomerate were based in Moscow and Anatra were based at Odessa. The war caused the industry to expand and smaller concerns appeared to try and satisfy the insatiable demands from the front. One such company in Russia was Tereshchenko who build a small order for twenty Farman pusher biplanes. An additional twelve unidentified aircraft are listed as constructed before the factory was closed and the equipment transferred to Moscow. Some of these other aircraft were likely to be German aircraft that had forced landed behind the lines. If they were deemed repairable such trophy aircraft were refurbished and allocated to Imperial air units. During 1915 B types from LVG, Albatros and Rumpler are known to have been used by the IRAS and later C types were rehabilitated. Such machines were highly valued and some Russian units were reportedly completely equipped with trophy aircraft. The Russian authorities paid the companies the same price as a new machine it was reported. Reading between the lines it looks as if Tereshchenko may have used the experience of working on German machines to produce an in house design. In August 1916 the company apparently had a meeting with Anatra engineers in Kiev. Tereshchenko needed a more powerful engine than the Russian Mercedes copy from Duflou and Constaninovich which only produced 100hp. Anatra had access to the 155hp Salmson radial but such was the demand none could be spared. But, they did suggest an improvement to the original design which was in effect an intended higher powered copy of the Rumpler B1. Anatras latest design was a two seat reconnaissance machine that was capable of accepting larger engines as they became available. Currently using 100-130hp rotary engines the Salmson would be next followed by the Hispano-Suiza. The secret were the swept back wings and the Anatra engineers suggested a similar modification. To speed matters up several pairs were sent to the Tereshchenko factory. But, while successfully adapted to the Rumpler fuselage, the design was destined to be a basic trainer without additional horsepower. Salvation came from Duflou and Constaninovich when they asked if Tereshchenko would test an improved model of the Mercedes which promised to deliver 160hp. Before the end of the year the bugs had been ironed out of both engine and airframe. It is believed eight aircraft were delivered to the IRAS where they were regarded as trophy aircraft and allocated to units already using such machines. Bolshevik agitation saw production curtailed and the factory was closed and relocated to Moscow.

The first task was to enlarge the cockpits. I have a sanding bit for the hobby drill which soon created a couple of neater looking holes. Next was to make a cut out in the lower fuselage to accept the wing. This allowed access to the cockpit area. The Emhar has a floor part with seats which only took a minute to make fit the fuselage. The rear seat was cut off and repositioned. A hole appeared from under the original seat position which Iím going to utilize as a camera trapdoor. A T shaped bit of sprue will act as the camera and round number tags will suffice as magazines. Not that much will be visible when the observer takes his seat.






When the fuselage was built several bulkheads were incorporated for strength and lining up. Itís still quite robust so I thought dismantling would cause too much damage. This mean I couldnít access the engine compartment to install an engine from the front. The only way in is from above so Iíve used the cylinders from an old Airfix Albatros attached to a slice of 60thou card to reach the floor. Manifold pipes were made from 20thou rod. The exhausts will be made from something similar and Iíll see whatís in the spares for the stack. The gun ring is laminated 10thou card which was wrapped around a dowel then filed to shape. I usually use copper wire but thought Iíd try this method. For the prop I found a couple of separated blades and a retaining washer and Iíll see what it looks like. Not the best photos, just trying to show the sprue camera and Emhar innards.

This is going to be a very interesting build

Before I forget the nose section was extended with laminated card which was then cut and filed to shape. I was going to scratch the tail planes from card and base them on the original Rumpler triangular design. But I have several Hannover biplane units spare so went for a modified set up. The fin had to be increased in height with card so that the rudder and fuselage depth matched. The upper tailplane is painted Imperial colours and the roundels are leftovers from an HR Niueport. Iíve used the Emhar undercarriage and got the rear gun ring in position. The Anatra company used a Germanic looking gun ring so I figured on Tereshchenko getting specialist supplies from an established company and Anatra is next door in Russian terms. The mgs will be Lewis guns though. Top wing next and Iíve managed to scratch a leading edge radiator. Progress so far.  Regards, Steve

Coming along very nicely  :thumbsup:

What paint do you use for your "doped linen" by the way ?

The CDL is Revell SM314. Its more yellow than HU121 Stone which I also use. There is such a variation of CDL that anything close will do as far as Iím concerned. Iím actually getting very low on supplies so will have to use white tainted with SM314 in future. Iíve cracked on with this one and got it finished. Iíd used the interplanes elsewhere so used some Contrail remnants and 30x60 thou Evergreen strip. The Lewis guns are courtesy of HR and Roden and the wheels are white metal spares. So here we have the Tereshchenko V, a reverse engineered Rumpler married to Anatra wings which were based on licence built Aviatik aircraft, serving on the Russian Front, in early 1917.  Regards, Steve

Thanks for that I normally use Humbrol, but I like the look of that colour  :thumbsup:

That really has come out well. Well done sir  :thumbsup: :thumbsup:
