Pfttt.. I can`t keep up with the speed on the forum.
May I go back to #8802 by Skytrain10, the Turkish delight twin.
It was started by THK (Türk Hava Kunrumi Ucak Fabikasi) as the THK-5 and developed by former DWL/RWD engineers from Poland which had gone to Turkey. THK built at least 3 including one for Denmark as air ambulance.
In 1952 TKH`s activities were continued by MKEK (Makina ve Kimya Endustrrisi Kurumu) and the design became the MKEK-10 (aka TKH-5A).
As far as I could find out there was never a TKH-10, this designation often erroneously being used (not in Turkey!) for an ambulance version of the MKEK-10.
The picture shows a THK-5.
