Sounds like you ran the gauntlet of the range! Some of them real oldies, however I'm glad to note you never encountered the needle rollered cam followers.. The only quads I encountered were on drilling rigs and they were about the oldest I worked on. The strangest were Stevenson pump units where the engines were mounted with the crankshaft vertical. Later I was involved with 92 & 149 series before I got mixed up with the bigger stuff like 567s & 607s. Mind you that was last century.:-) With the price of petrol going the way it is, I've been mulling over whether I should throw a 6v53 in my Chev truck, still dickering over the purchase price, though.
