Eagle 6 Lever Pancake Padlock

[candado3]

I have an old eagle 6 lever pushkey pancake padlock that did not have a key and though I was able to get it open there was no spring in the shackle and things were pretty gritty inside. I decided to try to take it apart and repair it. I had taken a few other 6 lever pancake padlocks apart but this was by far the most difficult to get the two halves separated.
I was also surprised at what I saw inside (besides the caked in dirt) it did not look like any of the other pancake lock workings that I had come across in my own locks or any articles, photos or videos that I had seen. I then decided to take photos and post them here in case anyone else would like to see how this lock works.
The lock had a lot of dirt inside, that appeared to be a mixture of hardened graphite and oil?. I carefully disassembled the lock and cleaned all the parts. I thought that the brass shackle spring had broken but in fact it was worn down and the ridge on the shackle that it rests on had been worn down and would no longer hold the spring in place. I made a new spring from some brass wire that I was able to scrounge from a local spring shop and filed the edge of the shackle ridge so that it was flat and held the spring in place.
I reassembled the innards of the lock and my next step is to try and make a working key before trying to put the two halves back together.

The first two photos show the top and bottom part of the case.
