bsa, it's great that that beauty has stayed in the family.
Not long after my dad got his first A-5 he gave me his L.C. field grade 12 ga. 30"" full & mod. that was a wedding present from my mom in'41. Several years ago I actually toyed with the idea of having 4" removed, a set of mod. and imp. cyl. chokes installed and slaying quail with it.
Needless to say, I DID come to my senses and left it alone.
