Here are two coke bottles bottled in Piqua Ohio. The one on the left I found a cpl months back or so. The one on the right I found sticking out of th river bank today. The one I found today cleaned up decent with just some soap and water. I did notice a few differences. The one on the left has more pronounced embossing, sides are pleated, and it is a 6 oz bottle. The one on the right is straight sided, embossing not as pronounced, and it is a 7 oz bottle. Both are stamped LB on the bottoms. I assume the one on the right is the older of the two. They both read PI-QUA-LITY, COCA COLA BOTTLING WORKS, PIQUA . O. Let me know what ya think bottle ppl. I love to hear what the better informed have to say. Is the one on the right what is called a straight sided soda???
