Help needed

[Ambulanced]

I think you have to push back the trim ring and there should be a roll pin at the base of the handle to tap out. I want to say that it is a square shaft that is pinned to the handle but I'm not sure. Good to see you fired up on the 49 again.

So I am messing with the 49 today, all inspired after Asheville and shit, and I can not for the life of me figure out how to remove the window and door handles on the inside of the door. I know it will end up being some simple thing, but it has me boggled at the moment.
