Vintage Vacuum Gauge Reactions Manual Sears Roebuck Paperwork Mechanic 1970s?. The pages are light yellow in color. Many creases and areas with discoloration. This item will be folded into thirds when shipped, as that is how it naturally sits due to the way it was stored. PLEASE NOTE: if you put this item directly up to your nose, it has a “grandmas house” scent from age. Thanks!
