Wouldn't it be appropriate for the Kl 153 to get its own separate topic now?

My latest attempts to improve my CAD reconstruction lead to some changes: Narrower
center wing (as already mentioned), longer and more protruding nacelles and somewhat
shorter tailbooms.
A question from my side (could be important to me, because of using that CAD software):
Is this a full-scale, or a sub-scale mock-up ? Since I started, I thought it to be full-scale, but
I'm not quite sure anymore. Judging the room, which could be a standard workshop and the
model hung down from the ceiling, it could as well be relatively small, maybe explaining the
low level of detail.
My next step will be to try to incorporate details from other Klemm types, mainly the Kl 35,
engine cowling, prop and probably hinge lines. That means, getting deeper into the field of
speculation, but still still as "educated guess", I think, and hopefully allowing to estimate the
main dimensions.

I left the firm ground of those two photos of the mock-up and entered the twilight zone of
speculations. I used the engine cowling of the Kl 35 (why develop a new one ?) and followed
the shape of the wing of the Kl 107. Klemm didn't use horn balanced rudders on most of his
designs, that determined the fins. I decided, that the section above the windshield actually
was a transparent panel, because due to the very steep angle of the windshield, view upwards
would have been limited either. Not sure, that those quite fragile looking landing gear struts
wouldn't have needed additional support and if the inner wing would have carried flaps, I'm
not sure either, but as a successor to the Fi 156 good STOL performance would have been
mandatory. And other details like trim tabs, or doors surely would have been there, but shape
and position is just guess work, of course. Source grade 2

My philosophy is always as follows when someone ventures into the depiction of little-documented projects: until someone can come up with a better work based on newly-found evidence, yours is the best and most reliable plan that ever was on the subject... And so I congratulate and thank you for this!!!

Nice drawing, Jens. I am slightly puzzled that something also meant as a spotter aircraft should have this few windows, small ones too. Maybe a production version would have had this corrected.

Yes, I was wondering about this, too. It looks much more like a light transport to me, but maybe
the mockup is just of the basic version and differences to other versions would have been similar
to those of , say the Fw 189 recce and trainer, or even attack version.
BTW, many thanks again for your great co-operation !

... and some colour !
The Kl 153 was mentioned as a successor to the Fieseler Fi 156 and although I agree
with Arjen, that at least this variant doesn't really look like an observation aircraft, I
used a Storch paint scheme from the North African theatre as a pattern here.
As a light transport or SAR aircraft it could been useful there, too.

Can someone translate the handwriten specs, comparing the "Späher" with the "Storch"? That would be great! Can't wait to ser your renderings, Jens!

IMHO the right RLM-designation is Kl 153.
The Fliegerrevue magazine is well known for its typos. :-/
