Roy, it's a relatively common catalog in a group of relatively rare catalogs. You won't find Lefever Arms Co. single barrel traps. The single barrels were made by the D.M. Lefever Company of Syracuse, Bowling Green Ohio, and maybe a couple of other stops. This company, using a few different but similar names, made what appear to be boxlock type actions. Some were boxlocks, but some that appeared the same , were triggerplate actions. Their period of life was 1901-1906, plus or minus. Lefever Arms Co. was operating at the same time. Your catalog value might surprise you if you put it on Ebay. I never paid more than $75 for one, but I sometimes see them offered for many multiples of that.
