I just got a return message from Dr Murat ?zveri.
He confirmed my mistake about the bow on the picture I have posted, the bow is, like Daniel wrote, a Grozer Junior. But he was also kind to write me quite a few details of the new bows that are being made now in Turkey. I think that probably this information would be also interesting to others so I asked him if I could post the message here, so here it goes:

I've had the new bow made by the Turkish bowyer. It's the bow you see on the picture below (back, in my hand), with our regular Grozer Turkish base bows (front, in the hand of Yavuz).

The other two bows were sent by Grozer to Vsetice for testing. The Turkish Junior is a short and good looking bow but is extremely slow. This model is the one which is on the photo you showed me. It may be suitable for kids and younger archers but undoubltly it's not for adults. The other model was a recent invention which I liked better. There are no string bridges unlike the Turkish base model, a feature that I liked; and the bow's energy storing capacitiy is amazing. I have tested all the models and got their force-draw curves. The chronograph measurememts are not completed, so I can't tell you anything about the efficiency but the velocity seems to be awesome too.
So, comparing these two "adult" models, our new model ("tirendaz" is the offical brand name now) is the one which is closest to the original design. Bows between 35-50# of draw weight are very good in efficiency (Mehmet Golhan-the inventor- made a 80# prototype as well as a shorter version for horseback shooting, but I haven't tested them yet). Grozer's new model doesn't look very much like the original but the 35# prototype I have tested stores as much energy as a 40 pound Turkish base does. The energy storing capacities of Turkish base and "tirendaz" is almost similar, but tirendaz is lighter in mass, which would provide better speed (I'll tell you definetly after completion of chronograph measurements).
Murat?
I thought I would also post the link to the article about those new bows made in Turkey:
