I do have several other questions:

1. the Dynamo needs to be turned around to run off the flywheel, is that correct?  what is the output voltage?

2. the funny spring loaded oiler does look like a threaded insert into the original oil cup.  It has been there a long time given that the patina seems to match. Has anyone ever seen one like that?  Looks like it will screw out, then just need to make a cover.  However as it has been on it a long time it might just stay as keeping it "original"

3.  Arnold's 4150 has a Gauge on it, mine does not.  was that optional? or just on some and not on others?  Gen has a 4160 D9 that has the gauge on it.  I will post it sometime. 

Thanks for any additional information.
