Hey guys,
I stumbled over these Bokor designes quite a while ago.
And not only Bokor also the other early aviation of Hungary has to be further researched, while most of the austrian part of the double-empire is well documented. Thanks to R. Keimel but not only him.
What ever there is written on the tail of this biplane it is nothing that would hint to Bokor by any chance. I turned it a few times but could not get something useful out of it, even in hungarian language. Therefore I think it is rather a name of a designer, which I don't know. (Maybe "DIOK No.II"

)
Unfortunately Herb Sieger didn't answer me and ceased to update his page one year ago. Just I wouldn't start to work on all the countless questionable entries.
The US machine is pictured again at Herb Siegers list in the 1908 section,
built by a "T. Bocker" - from a source that is not available anymore.
The name Bokor is most likely of hungarian origin. There it appears more often than anywhere else.
By the way
"háromfedelű" means triplane.
három = three, the latter part is referring to wings.
Complete it should read “háromfedelű repülőgép“ – triplane aircraft.
Cheers
Aquilius
