Re: Year? and what is it worth?
No serial number means it was made before 1968. New law went into effect then required numbers on all guns. Before that many, if not most, inexpensive guns were not numbered.
A 311 in "good" shape should be somewhere between 3 and 5 hundred. Closer to the three end, most likely.
