Greetings I have an 86 Winchester in 45-90. It has the "single set" trigger. I am missing a small piece that attaches to the hammer called the "FLY" which allows the single set function to operate. The trigger will work in the normal manner but the single stage is better. I also am looking for brass also. Any and all leads will be very welcome. Thank you.
