lubracating 1904 orient buckboard engine

[JamesLay]

i am having a new sleeve installed in my cylinder and new rings on my piston and would like some feed back on the finer points of lubracation. like how many ounces in crankcase? was the orignial oiler pump or drip feed (on 1904) how do you know when to feed oil to engine with the pump style feeders? i have heard 8 drops of oil a min. with the sight glass drip feeders.but looking at pictures the 04 oiler looks like it might be a pump . i saw a period ad that stated the oiler held 3 ''charges'' of oil for a 90 mile range.  (daisy catalog) also how does the crankcase vent? is the small brass cap next to the exhaust valve guide a vent or oiler?   thanks
