Von Zech

Von Zech published the German language version of Zion’s Watch Tower until about 1891, replacing it with Die Ernte-Sichel: Monatliche Zeitschrift zur Verbreitung der Erkenntnis und zur Förderung der Interessen wahren Christentums. (The Harvest Sickle: A Monthly Magazine for the Diffusion of the Knowledge and Promotion of the Interest of Pure Christianity.)

I need scans or clear photocopies of Die Ernte-Sichel published between 1891 and 1895. Can you help?
