Mike, I assume that Larry did not see a picture of your bow. According to old Damon Howatt ads, it's a 1960.
The Archer's Magazine, January 1959, Pg 3;
The National Bowhunter, March 1960, inside cover;
The National Bowhunter, March 1961, Inside cover;
As you can see, the '59 riser is different shape and laminations, the '60 is an exact match and the '61 has the same shape but additional laminations on the belly that your bow does not.
I hope this helps to clear it up.
Brad
