Recently, I have seen at least 3 or 4 decent quality and condition no name boxlock ejector guns go for sub 1K. Similar to this:

Seems like a soft market. I have only sold a few side by sides, all lower grade non-ejector (all I can afford), but they have taken a lot of time and effort to move. The lowly boxlock gets no love, unless it is a Parker or AH Fox apparently smirk
