  Baby Wolf.JPG - BABY WOLF - Baby Wolf aluminum and brass No. 603 lamp, 7 1/4 in. tall to top of hook ring, 2 1/2 in. base dia., marked on brass tag on top MINE SAFETY APPLIANCES COMPANY PITTSBURGH, PA and stamped with Dept. of Interior Bureau of Mines seal and marked PERMISSIBLE METHANE DETECTOR (MAGNETIC LOCK) APPROVED FOR SAFETY, DURABILITY AND EFFICIENCY APPROVAL NO. 207 ISSUED TO THE WOLF SAFETY LAMP CO. OF AMERICA, INC. on brass tag on bottom, corrugated  bonnet with magnetic lock, new old stock condition, owned by an old miner in the Pittston, PA area  (Approval No. 207 was issued by the US Bureau of Mines on November 21, 1924 to Wolf specifically for the Baby Wolf Methane Detector.  The Baby Wolf is the only flame lamp to receive Bureau of Mines approval as a methane detector.  It did not receive approval as a safety lamp because the light output did not meet minimum requirements.  The Mine Safety Appliances (MSA) Co. did not carry the Baby Wolf in their 1958 catalog but it’s not clear when Wolf ceased its production.  The Wolf Junior with a straight bonnet and the standard Wolf lamp in various forms were still listed in 1958 prior to MSA buying Wolf.  MSA was a primary dealer for Wolf lamps long before they bought the Wolf Co. and it’s thought that Wolf added the small MSA oval tags to lamps that they sold to MSA – the tags are very similar to the Wolf tags in shape and size. MSA has been in business continuously since 1914.)
