Here is the date code marked on the gun: XIX (1963?)
There is a drawn bow under the barrel and if I remember correctly it is stamped Delfino on the left of the barrel.
Trigger is single, non-selective is there are extractors not ejectors.
Side plates still show color case hardening and the stock has some dings, but the checkering is sharp. Barrel is 90% blue with no dents or scratches.

Worth $485?
