Hi Ray,
Between 1902-1909 Stanley's had their engines running in a copper dust case, containng no oil. This was called a "dry engine" Every 50 or so miles you would have to get out and get under, open some sliding doors on the dustcase and oil the motion work by hand. From the 1909 model U and R, both 20HP models, Stanleys fitted their engine with a casing containing oil, so this hand procedure was no longer needed. Soon however they found that if the piston and valve rod packing glands started leaking, the oil would be contaminated. Thus they redesigned the engine casing so that it was now in two sections, instead of the previous all in one, the cylinders were covered in a copper case holding insulation on, behind the packing glands there was a steel diaghram plate which held on a copper cover containing the crankcase oil. There was another diaghram plate on the diff, thus keeping oil leakage to a minimum, as well as oil/water contamination. The packing glands were also now easily adjustable, the engine case now not having to be removed to do this. This was kept from 1909 until the end of production in 1926. Hope this is understandable. Basil has done this convertion to his car, but has a small copper section between diaghram plate and the cylinders, so the visual appearence of 1908 is the same. George Hounslow.
