I have a Canjar trigger Model 700-1S/2 for Remington 700 (and 40X, 721, 722) rifle. It has a 3/8" wide trigger shoe for the normal target trigger, and includes Canjar's signature set ("hair") trigger. Trigger was purchased around 1970 for a custom rifle that never materialized. It has the original documentation.
It is unused and has no rust. However, after 40 years, it should be cleaned and relubricated. Cleaning, lubrication, installation and adjustment of this trigger requires serious gunsmithing skills and tools.
