Raimey,
I didn't check pull weight before I pulled it all apart. I'll let you know when I get it back together. (It wasn't heavy enough for me to note it.)
The sear-nose interface is quite pronounced. Pushing on the lever to release the striker with a thumb takes a good bit of effort. More of a 'hook'.
The pivot points on the trigger blades and sear lever obviously assist with the pull weight.
Obviously I pulled it further apart....
Parts are cleaned of 100 years of gunk. Starting reassembly. The only parts I did not take out were the top lever and locking mechanism. I didn't want to bugger the screw.
