Don't be rush please,the Laz-6 was a side-by side two-seat
trainer project,

In April 1946, the Yugoslav Air Force announced a competition for a two-seat training aircraft design. An invitation was also sent to the Air Force Headquarters for Bulgarian designers to participate in the competition. In the shortest possible time, Eng. Lazarov formed a design group in the Lovech factory and began work.
“I had to develop the “LAZ-7” design within 40 days. - He wrote. - In addition to it, I wanted to present another of my “LAZ-6” designs, which, although it did not fully meet the conditions, because its two seats were next to each other instead of one behind the other, was completely suitable for the purpose. The Air Force Technical Directorate sent only the “LAZ-7” design to Belgrade, and the “LAZ-6” design was returned to me.”
The design of Eng. Lazarov and the Lovech designers won second place in the competition, and he himself was awarded a prize of 15 thousand dinars.

Also,we spoke about Lazarov aircraft and projects in this thread,and
in Post # 1,you will find my search from a Bulgarian site,which said;
the Laz-5 was a single seat fighter.

Even in Reply # 10, my dear Adrien translated another site,which
indicated to Laz-1 to Laz-4,

Will follow four-passenger Laz-8 modernization carried out by a young factory team and the armory by the BBC as Laz-7M, microlight aircraft to train fighter pilots in aerobatic, remained only as a prototype Laz-12. After some years of aviation "historians" began retrospective of "Lazaruvane" and other structures eng. Lazarov, the planes of the series DAR (DAR-6 / Laz-1, DAR-6A / Laz-2 DAR-9 / Laz-3 DAR-10A / Laz-4 DAR-10F / Laz-5) produced in 1932-1941, at Bozhurishte. This is incorrect because the first plane, named "Laz" is Laz-7. And none of the "godfathers post factum" has not considered where I go in this Laz 6?.

He did indeed! And thank you for quoting the refutation of the Laz-1 through Laz-5 designations. That said, notwithstanding its double negative, the final sentence is hard to parse.

At first we can say,there's no prefix "Laz", so for Lazarov
early aircraft,we can say,

No.1 was the same as DAR-6 & DAR-6A
No.2 was the same as DAR-9
No.3 was the same as DAR-10A
No.4 was the same as DAR-10F
No.5 was a single seat fighter project

My dear Apophenia,I submitted to you the proof of existing
for Laz-6 in Reply # 40, again;

the Laz-6 was a side-by side two-seat trainer project,

In April 1946, the Yugoslav Air Force announced a competition for a two-seat training aircraft design. An invitation was also sent to the Air Force Headquarters for Bulgarian designers to participate in the competition. In the shortest possible time, Eng. Lazarov formed a design group in the Lovech factory and began work.
“I had to develop the “LAZ-7” design within 40 days. - He wrote. - In addition to it, I wanted to present another of my “LAZ-6” designs, which, although it did not fully meet the conditions, because its two seats were next to each other instead of one behind the other, was completely suitable for the purpose. The Air Force Technical Directorate sent only the “LAZ-7” design to Belgrade, and the “LAZ-6” design was returned to me.”
 
For Lazarov,

No.1 was the same as DAR-6 & DAR-6A
No.2 was the same as DAR-9
No.3 was the same as DAR-10A
No.4 was the same as DAR-10F
No.5 was a single seat fighter project
