I'm restoring a ECO Model 93 air meter and need information on the reel lock pawl. This assy. is missing from my meter. This is the assy that holds the air hose in position when you pull the hose out. Some of the items I beleive are missing are #72-74 on the parts list. These are found on Fig.8, reel mech. parts Model 93. If I could just get pictures of the items, or assembly then I could possibly reverse engineer the parts. If any of these parts were for sale I would be interested in purchasing them. Any help would be greatly appreciated. Thank you for your help.
