Usually a few of these on Ebay. There is an early and a later version. The later one is "Service Manual Passenger Cars Starting 1969 Series 108, 109, 111, and 113". The early one is "Service Manual Maintenance, Tuning, Unit Replacement Passenger Cars Starting August 1969". You really need both if you want to cover the W113 series. Bound versions should have all the supplements added and should be complete. Be careful of the "loose leaf versions" Supplements had to be added manually to these by the shops using them and they may not be complete.
