Jena model engine range... and Aktivist 1956 test run

Wecome for this new edition! This time I feature the JENA story.AS there is not a lot info about this lovely Jena engine range to find on the web,I deside to bring a video on that subject.
The Jena concern is world wide known for there high precision products on optical instruments,lenses,range finders,microskopes and many other things as well in WWII bomb sights,periscoopes and other high precision miliitary hard ware.
After the war the go also as other precision companys in the production of model engines.
From 1951 till 1965 they make a range of lovely engines.Mr. Walter Hercher and Karl Zacharias were the brain childs for those engines.Later on,alsoMr Walter helmuth Kratch from the "Kratmo" engine fame join the team at the moment ,when they design the Glow 2,5 in 1965.
AS said in the clip,the early engines are the best with a very cosisten quality.Because of the comunist regime,later on they had issues to get some times the right steel and good ball bearings for there production.
Never less,I found them a very sound design,good power,and clever made,with attention to small details.
The engines come regulary for sale on ebay,so as sad,try to go for the early types,and you should be not disapointed,if you find a decent engine.
