Bill,
 
I received your spring today.  The results follow:
 
Load (lbs)        Deflection (inches)
    1.7                    .125
    3.3                     .250
    4.9                     .375
    6.6                     .500
Tolerance for load = +/- .05 lb
Tolerance on deflection = +/-.0005"
Rate = 13.2 lb/inch +/-.1 at .500" deflection
Spring height at coil Bind is  .405"
Free Length is .970"
Max deflection is .565" 
 
This should get you in the right ballpark.  Your spring will be returned tomorrow.
