AYCE (Arriolia Y Compania S.L. Spain) AC60-A2 YA4 Boring Machine. "Technical Service Information" and Parts as Sectional Drawings. Includes a copy of the maker's Technical Sales and Specification Catalogue. This manual was issued by the makers on "Banda" sheets - a crude way of reproducing pages that fainter with time. The reproduction is, therefore - despite work to increase the contrast - not to our usual very high standard.
