Hello. I just picked up a Cogswell & Harrison rifle in 300 H&H. 68xxx. I have read the posts featuring the 404 and 375's. My rifle seems to be one of the "specials" built thru 1953, according to the posted literature. My question is about the bottom metal and release. Pictures of this series of rifles seem to have a release located in the trigger guard. Also, I read about the use of aluminum in the magazine and how it can become deformed by hard bullets. My rifle has a steel magazine well. It also uses a lever to open the floor plate, not the trigger guard button. Does anyone know anything about these rifles that might help me figure out what model that I have? Or might the lever release just have been an option? Thanks for your help. Gary
