Show quality 4 bar OEM Messko-Hauser tire gauge marked Mercedes for 190SL cars from 1958-63. [Early  cars came with the common 3 bar gauge.]  The blue wooden box is in spectacular condition and it comes with the very, very rare ORIGINAL perforated paper insert giving the tire pressure specs in various languages. This is not a laser copy like  you almost always see on eBay listings. This is an original perforated, folding paper insert unique to the 190SL cars. [The fake ones are two-tone with white on the reverse side. Beware of "original" paper inserts where the reverse side is hidden. Other fake ones have normal folds with no perforations.]  These gauges came  inside the on-board tool kit each buyer got with each car. An original gauge, box and paper insert will be the rarest item in the on-board tool kit and is without a doubt the hardest item to locate. Here is a rare chance to get one right now at a fair price. Shipped fully insured, signature required with tracking provided day of shipping. I have 20 years of positive feedback selling Mercedes tool kits, so bid with confidence. No-hassle right of return for any reason.
