Troops,

My fathers' mid 60s Charles Daly import of the Miroku O/U (SN 203,xxx) has a bit of a mystery.
First: It has no Charles Daly markings -- only Miroku/Kochi
Second: All Google Guidance to the contrary, it has no Choke markings on either side of breech end of the barrel (See Pic-1)
Third: The Instruction Manual (somewhat worse for wear) says "Full and Full" on page-2
Fourth: The bottom of the barrel recoil lug recess says "IMP" (Pic-2)

My first thoughts are that the Bottom barrel is Improved, and the top either Improved-Mod or Full.

Any additional thoughts from the experts?
