Supercharger lubrication

[Conny Gillstrom]

I'm working on a superchaged Ausin Seven racer 
Have some difficulties understanding a few things, espacially the lubrication of the supercharger.

First of all the supercharger is mounted towards front from engine block. All photos of other I have found superchargers seem to be mounted the other way around, beside the engine block below exhaust manifold. 
What would the orgon of this setup be?

Next there is a number of nozzles, mostly for lubrication I assume, that I need to understand how the should be connected.
See the photos where I have marked the different nozzles with red letters A-G

A: In the rear on engine block
B: Adjustable valve on supercharger
C: Threaded hole beside B
D: Center of crankshaft (assume that this is oil pressure out?)
E: Threaded nozzle with on/off valve on front end plate of supercharger
F: Second nozzle on front end plate of supercharger
G: Nozzle on front of engine block

Would very much appreciate to get some guidance on understanding and how to connect these nozzles / lubrication points.
