I've never had one of these apart, but my impression is that one end of the pin 
is knurled and that you have to push the pin out from the other end. I think 
the knurl is on top, so that oil can get around it when you oil from above.

I've never worked on 3-bolt hinges before, but the topic comes up here 
frequently. I guess they were used for all the notches, not just the early 
ones. I'm surprised to see that you have one of each, however. I had assumed 
that cars with 3-bolt hinges had them on all 4 hinges. 

For those who are familiar with these: Is David's photo normal, other than the 
broken parts?

As for the welded holes, a welder is a wonderful tool, but once some people 
learn to use one they tend to assume that it's the perfect repair for 
everything. It looks like parts of those hinges have some brazing material on 
them. If so, you won't be able to weld anywhere near there. You'll have to get 
rid of any nearby brass or copper before you try to weld.

I also see that these bolt holes aren't countersinked like the later 2-bolt 
hinges are. What kind of bolts did these doors use, and are they all this way?
