Vintage Singer sewing machine manual. "Singer Slant-O-Matic 503 Special". Published by The Singer Manufacturing Company in 1961. Good condition. The paper covers still have bright color. They show considerable wear, however. The interior is very good. No writing, torn or chipped pages, smudges or foxing within. This book measures approximately 0.25"D x 7"W x 5"H and has 96 pages. Three little tanned sewing related newspaper articles were tucked inside (see photo.) Sending them along just for fun.
