I'm presently working on some projects and would very much appreciate any information related to the Fraser Patent Single Trigger. Anything from literature, advertisements, etc. would be most welcome. Would also appreciate the source of information so I might add it to my library as well. Below is a picture from a Fraser magazine rifle showing the internals of the mechanism that may be of interest to members.

The project I'm working on can be found in the following post:
