ADDED ON MARCH 3: I HAVE FOUND A FULL-PAGE CENTERFOLD D & M ADVERTISEMENT FROM A 1923 MAGAZINE SHOWING A BOXING BAG VERY SIMILAR TO THE ONE UP FOR AUCTION. PLEASE CHECK ALL THE SCANS.This is a vintage leather speed punching bag produced by the Draper-Maynard Co. (D&M) of Plymouth, NH. I am guessing it is from the (1920's ?) 1930's or 1940's but I can't be sure. It has a manufacturer's number "DG687" on the side just below a nice "Lucky Dog" logo which was the rather famous trademark of this company. D&M products were widely used and endorsed by professionals (Babe Ruth, Mel Ott, etc.) in the 1920's and 30's and are highly collectible. Perhaps someone may be able to pinpoint the exact vintage of this bag using the #. I appreciate any information. On the bottom of the bag it says, "Inflate Not Over 3 Lbs." just above a needle hole (no needle). The bag may have come with an inner bladder but there is only the reverse of the leather on the inside, so it does not hold air at this time. There is a nice leather tongue at the top and a heavy leather loop probably used for attaching the bag. The bag is in vg condition with some general wear and a little fading. The leather is soft and maleable. There is a black lace strung through the grommets but I am not sure if it is original. I have filled the bag with plastic to expose its proper shape. Please check the scans and ask questions, if any, before bidding. Winning bidder pays exact priority mail postage (1 and 1/2 to 2 pounds). Check out my other items ! I received a response to my request for information from Ebay User jrm77777 (Thanks, I appreciate your effort). I am including the information relating to the speed bag: "...Your item is from 1937 or later. After co-founder John Maynard died, the company was sold and moved from Plymouth, NH to Cincinnati, OH. At that time, they began using DG at the beginning of many of their model numbers ... This was true of baseball and boxing gloves as well as speed bags and numerous other items. Also, in the 1920's their logos specified D & M Sporting Goods rather than D & M Athletic Goods". Posted March 12, 2011.
