The very late 1850s had the over/under available, while the early had the two speed shift like the 1100s had. The 9B SN 1100s were much improved over the early ones, dad bought his 1100 new in 1971 and has 7000 plus hours now, head has never been off. Not sure about 1850 hydraulics whether open or closed but 1100 was a closed center system. Injection pumps had changes too, 1850 and early 1100 had the small quill drive shaft that were prone to break, later 1100 came with the uprate hub drive that Oliver changed to only when a failure occurred for service. 1850 pumps had 9MM plungers while the 1100 came with 7.5MM plungers. Like most used equipment, depends on past care and parts support..
