Hello Everyone!
I recently inherited a 1945 H&R Topper M48 12 Gauge shotgun.   It is reasonably good shape.   The action seems to be tight and in good condition.   I am trying to locate whatever documentation is available for this shotgun ...... owner's manual, parts diagram, etc., before I strip it down for cleaning and possible replacement of worn parts.    And if anyone can tell me of a source for replacement parts, it will be greatly appreciated!
Any direction or help will be appreciated.  Thank you!
