General P. Elias Calles 1212 Upas St. San Diego, California
San Diego, California Very Esteemed Mr. Knoll, With pleasure I respond to your kind letter of last February 28, in which you express your wishes and projects to establish an airplane factory in Mexico, and you see to send me your information on capabilities and personal background. I have carefully examined your idea, and proceed to give you my opinion, as frank and sincere as you so requested. For some years to come, and while the consumption of airplanes is so small in my country, I believe it will not be a business to establish such an airplane factory in Mexico. Hoping to have satisfied your wishes, I remain your attentive friend and humble servant, P. Elias Calles |
