Case Model LA Series Operators Instruction Manual Re-print. We had these re-printed from a very nice original manual we have. Some very minor smudging on the front and back cover came through on these re-prints, but don’t let that stop you. These pictures here do not do the manuals justice. 64 pages. Manual is dated 1948 and does not contain any hydraulic information. But it is packed with pictures, specifications and “how to’s”.
