The Iar80/81 are modeledpretty bad in game, but some users that sent Oleg half assed info are part of the blame.
You bring in half truths as well. The Iar81/iar81c did carry bombs. It's enough to google iar81 images and you'll see plenty photos of 81's loaded with a pair of 50kg bombs on the wings and a centrl 250kg bomb. Actually most 81's did come from the factory with the racks installed. On many planes, that were used as pure fighters, the racks were removed. The white 344 in your post is a clear example. The plane was based on popesti leordeni and did fighter duties against the US bomers. No point to carry the bomb rack since it just slowed them down in fighter duties.
I think you need to do a bit more research and then ask for changes. There's a newer book out, that explains all the versions of iar80/81 very well. You should get it,so you understand it a bit better and don't ask for things that would hurt more than fix, like other people before.

And no. The six 7.9mm guns IAR80 was not the most produced version. That was the IAR-81C.
There is quite a bit of confusion around about the IAR80/81 versions. Many were very close in mames and equipment, so the confusion is explainable. For example, IAR 80C and 81c were different versions the 80c came without bomb rack and used 4x7.9+2x20mm (mgFF) and the 81C version came from the factory with bomb racks, 2x7.9+2x20mm(MG151/20).
