Not as far as I know - too late to ask them now (except my dad, and he definitely didn't). Thanks for the translation - I'd never have managed it.
Well, it was just a joke, AFAIK the use of this writing was limited to German-speaking regions and after
the war, it dwindled and was only taught as our "beloved" subject calligraphy ...
But for someone, who is desperately trying to decipher such a writing, this site may be helpful:

.. or forward it to me, I'll try to help.

Was it considered to use the me 328 as a parasite fighters on the me 264?

Hi! Steam turbine projects.
"As I have previously mentioned in this forum, during WW2 there were a few projects for designing a steam turbine for aviation use.
The first of these was started by Junkers Moteren (Jumo) in 1940. The turbine ran on the test bench in 1941, but the project was shelved in 1942 in favour of gas turbines.

The specs for the Jumo turbine were:
Power - 3000hp
Turbine speed: 8000rpm
Propellor Speed: 950rpm
Weight: 800kg (I presume this only applies to the turbine itself and the reduction gearing, not the boiler and other required equipment).
Intake Pressure: 100atm
Intake Temperature: 550°C
Exhaust Pressure: 0.15atm


A further steam turbine design was also being undertaken by Professor Lösel and Dipl-Ing Pauker at the Technische Hochschule. This was to be rated at 4000hp.
Not much in the details for this turbine, except that the turbone would be roughly 1/2 the length and 2/3 the height of the Jumo 213 aero engine (ie about 1225mm long x 565mm high). It was also cancelled in 1942.

Steam turbines re-emerged in 1944 when Messerschmitt were looking for suitable engines for their long range Me264 "Amerika bomber". The first prototype Me264 flew with 4 x 1250hp Jumo 211s, taken straight from the Junkers Ju88, and the second prototype used 4 x 1750hp BMW 801 radials. Both were considered underpowered. The original concept called for 1750hp Daimler-Benz DB603s, but these were in short supply.

Various alternatives, including mixing piston engines and jet engines, turboprops and turboprop and jet combinations were investigated. Steam turbines were also investigated, with Professor Lösel's Osermaschinen company being asked to design and manufacture a suitable steam turbine."

Thanks for your appreciation, pegasus-san!!
Perhaps we can see the concept of Me264 America bomber candidate steam turbine engine through this Junkers drawing.
