Wright ratchet MN 60+

[Northwoods]

I picked up this Wright 3/8" on the bay yesterday and wonder what I should expect when I remove that big incorrect screw that holds the pall.

It is clear that the screw needs to be replaced.  I have seen several types on the bay, both roundhead slot screws and thin hex screws.  Not sure exactly what I should use to replace it.
And what will happen when I take it apart. 
I am sure some of you fellows have operated on a Wright.  I understand they are a bit unconventional.  Of course, that was its attraction.  And you have to admit that the price was right.
Any help will be appreciated.

Nice buy!

Take a look at this patent link, it may help a little. It was the earliest Wright ratchet patent I could find.

I doubt if you'll find anything in there you can't handle.

Thanks, Bill.  With my manual dexterity being what it is, I think I should assemble mine inside a plastic bag.  Especially if mine has the spring and ball inside the tooth wheel.  Looks like some have it, and some don't.
And I don't think I would want that rectangular coil spring to go zinging across my shop.
I see some other differences between mine and the others I have looked at.  My selector is more a knob with a backbone than a knob with an ear.
And mine has no date code.  Just MN 60+.  I would like to think that it indicates that mine was pre-date code.  That is probably merely wishful thinking, though.  I wonder what the + means.
I might have to get creative to find/make a suitable replacement for that big, ugly Phillips screw.  I just hope its threads are correct and haven't messed anything up.
I will be away for a while and won't be able to get to it before the new year.

Done.
Mine was extra gooey. The back of the faceplate indicated a 1947 vintage---same as me.
Pulled the incorrect Phillips screw and found a bolt to replace it. Filed all races down so it would clear the shifter. Then ground down the head to about 3/32" and polished it. Adjusted it for length.
Cleaned and greased it.
It is desert!
