Classic blade putter of the 1930's. Coated steel shaft. The steel appears to be in good condition. The coating is cracked above the hosel. 

The shaft is clearly stamped Mount Vernon N.Y.  Trade Mark   US Pat Off    1,662,712. 

The original wrapped grip is intact except  near the top. The end cap is missing. 

The hosel is pinned and the head is stamped    Stainless  George Kerrigan. The face is dot punched.

The sole is stamped  C.C. 3  (or B)  6(or 9) ??

Per research George Kerrigan played professionally.  Could not find the manufacturer. This could have been a custom putter made for George.
