1961 Model 50 timing cover

Nearing completion on my model 50 build and I have the proverbial 'bag of bits' for a timing cover. I can't seem to find a decent exploded view of where all the bits go. I have the 2 conical springs, 2 ball bearings, one large, 1 small and the 'top hat' which bears against the pump outlet, all out of the casing. I also have the l/h threaded piece which forms the main oil feed to the crank. Missing is the oil connector and spring for the crank feed.

Q1. Which way round do the conical springs go?

Q2. Does anyone have the sizes for the (presumably brass) oil connector. I have a lathe and the wherewithal to make the missing part. Is the spring available anywhere?

Q3. Am I correct in thinking there is no gasket for the timing cover?

thanks in anticipation.
