i find the plan listing of the A.M.A may this link will help you a little and add two images one for the model build per plan and the other is from a papermodel
Aircraft HL-was the first independantly built construction by ing. Józefa Medweckiego, a constructor working in a plane factory named „Samolot”(Airplane) in Poznan. After authorizing the calculations Medweck began on the half of 1926 with the help of a few professionals and friends the build of his airplane. The material needed to buld the model was partly bought, and partly accessibled by the constructors factory and he three cylinder engine Anzani was lent to him by the LOPP. The wooden sub-assembly of Medwecks airlpane was glued together in his attic and the construction was joined together in an empty workshop at the Poznans railway station. The airplane received a marking HL-2, coming from the surname of a famous American comedy actor Harold Lloyd. An interesting thing in the airplane was its right undercarriage wheel which was covered by linen, where the left wheel had unscreened spokes. Medwecks main goal was to take part in Te First Country Avion Contest in October 1927. In the early autumn of 1927 the airplane had test flying. The airplane was painted light red ( except the front of the fuselage which was made from sheet aluminium), it had a black marking on the front of the fuselage HL 2 and a picture of the famous actors glasses. On the 5 of October some difficulties began to happen. A pipe leading fuel to the airplanes engine broke and compulsive landing was needed. Before fixing the damages and finishing the flight to Warsaw the contest already began and Medwecks Avion- with the agreement of the commission –was able to take off beyond of the contest. Thanks to that it was possible to compare the results to other airplane results which started in the contest. After a nother compulsive landing, which-because of the engines breakdown- took place in a contest flight from Warsaw to Deblin, the broken engine was dismount out of the airplane while the airframe was ruined in a car crash when transported to Poznan. The wooden construction is only glued. The engine and the front part of the fuselage are covered with the aluminium sheet. The cabins are uncovered, covered only by a windscreen. Wings are made from a wooden construction, covered by plywood,with the look of a rectangle. The undercarriage is three-support made from steel pipes with to main wheels, absordering tail skids. Woodens construction control surfaces, hidden plywood, in the classic configuration.
