Contender for 1934 Challenge International de Tourisme. Note different landing gear compared to D-IJIP.

Klemm reworked the Kl 36 as the Kl 36B, freed from the empty weight restriction of 560 kg (1235 lb) of the 1934 Challenge International de Tourisme. This Kl 35B prototype had a Hirth HM 508 engine. It is listed as registered in March 1936, used by Lufthansa and written off in January 1939. A batch of 50 production Kl 36Bs was ordered with Sh 14 radial engines, but only seven or so were completed. Photo from: Böblinger Flughafengeschichten

The Kl 36B as built in a small series, powered by a Siemens Sh 14 radial engine. Some examples were impressed by the Luftwaffe as liaison aircraft. Photo from: Böblinger Flughafengeschichten

Another aircraft type designed for the 1934 Challenge International de Tourisme, the four-seat Kl 36 was the fastest ever Klemm aircraft, but none of the four participating Kl 36As completed the Challenge's 9537.4 km rally through Europe. They were powered by either an Argus As 17, as seen here, or a Hirth HM 8 engine. For some reason, three of them had this braced landing gear which looks like a hasty improvisation.
