Members are discussing the odors associated with the printing industry. How many were around during World War II and remember the smell of patching innertubes with a hot patch kit.
My dad was a rural mail carrier. New tires were impossible to come by and the gravel roads he drove over ate tires up. He'd take a worn out tire and cut the beads off of it and stuff it into another tire to try to avoid punctures. However, he'd come home about every night with flats to fix. When the weather was cool he'd bring them into the kitchen and get out the patch kit. First he rough the area to be patched with a buffer, then he'd clamp a patch kit on to it and light it. Something in the patch pan looked like cork and had a odor all it's own; kind of nasty and kind of pleasant at the same time. The heating material would burn out, he'd let it cool a while, then remove the clamp and pan and proceed to the next puncture. I think by the time the war ended some of his tubes probably had as many as 2-dozen patches on them. He would never use a cold patch with cement; he said they would come loose.
Getting enough gas ration stamps was a problem also until he stayed home one day and all the neighbors complained about no mail delivery. He always had plenty of stamps after that.
