    Dear Madam / Sir,

    It has been quite a long time since I missed James Hubert Gilmartin III owner of the Southern California Air Systems in LA. My name is Tsegaw Yoseph, professionally a chemist, male and an Ethiopian. I have worked as a company representative for Jim (James H. Gilmartin). It was about 6 years since I didn't see him. He has obtained investment license for industry business in Ethiopia. After he left from Addis Ababa his personal doctor has told me that he had a car accident in Peru.

    I am very much thankful for Jim, he tought me industrial businesses. Today I make furnace bricks, furnaces, pizza ovens, metal casting works, porcelain etc. The great things he tought me and his friendship always remains in my heart and blood. I appreciate and thank Jim he is such a great person and an excellent American citizen and he loves and cherishes helping people. His patience are also worth to mention. He is really a technological person and tought me how to make things from scratch in any industrial sector.He opened my eyes. Any one who knows his address, please extend my warm greetings and appreciations.

    Jim, may God bless you abundantly I really missed you!!!!

    Best regards,
    Tsegaw Yoseph
