Iver Johnson sidewinder

[old gun nut]

I have a Iver Johnson Sidewinder 22. Its in pretty good shape . When I got it in 1987 the finish was mostly worn off , so I bought a Parkerizing kit and refinished it. It has worked well ever since. It is double action but has developed a problem. The trigger will not return when it is fired. It must be returned manually. This happens whether it is fired single or double action.
I had our local gun smith look at it, but he could not repair it.
I have it apart now , but would like a blowup diagram to under stand how it works. If any one has such a diagram, or knows where I could get one I would appreaciate the information. Thanks OGN
