I found yet another photo 232.Good afternoon Tzaw1,
But tell me something, the picture you have submitted is it really the Ikarus 232 (predecessor of Ikarus 451)? Would you have more pictures of it?

I found yet another photo 232.
And, maybe this is an error, mayby notPosleratni nastavak eksperimentalnog projekta aviona sa pilotom u leżećem polożaju konstruktora Beślina bili su avioni 232 i 451. Na slici probni pilot Tugomir Prebeg pored aviona 232. (VOC)

Well this confused even myself, but I believe I have finally figured it out. Prewar experimental airplane was designated Ikarus B-5 and it had fixed landing gear. As prevoiusly mentioned, I will post picture of this plane as soon as I can. As long as projects "232" and "451" are concerned these were both build after the war.
So, there were three plane types with pilot in prone position build in Yugoslavia and they were all designed by Dragoljub Bešlin. Reasoning behind this concept was that pilot in prone position will be able to better cope with g-forces when pulling out of the dive. First experimental project, Ikarus B-5, was therefore envisioned as a dive-bomber. One prototype was build in 1940 but flight tests were not concluded because of German attack on Yugoslavia in April 1941. Second project was Pionir 232 (one example build in 1947) and the third project, developed from Pionir, was Ikarus 451. There were two examples of Ikarus 451 build. First prototype 451/I made its maiden flight on 22 September 1951 with Lt. Radivoj Glavičić at the controls. Second prototype 451/II (now exibited in the museum) flew for the first time on 26 February 1952 piloted by Captain Tugomir Prebeg. After two years of testing project was eventually abandoned.
Here is the link for few more pictures of Ikarus 451:

OK, guess this little bird:
Ok, I'll take another crack at it.
It seems, that is a small difference.
The nacelle below the fuselage is smaller and right at "232" (at foto left).
But at "451" the nacelle has central postion and is a bit greater.
And wingtips are cutted, it seems.
