thats koloman mayrhofers site . he does exquisite work. very authentic and researched. he was around doing it before there was much buzz in new zealand. hes a very nice guy as well, i corresponded via email with him back when i was a member on another ww1 aero forum. i used some of his oeffag albatros pics to help detail my model especially with regards to the gravity fed reserve fuel tank hidden in the upper wing.
