Yeah-but, seeing as they are not a portion of the circumference of a circle, they do not have a 'radius'..It'll be on the box - hence my ..............................
I was thinking more of how you identify the 'size' (sic) of the point..
I think the 'point-number' is the number of degrees, between the straight and diverging rails?? - So a lower number is a 'gentler' divergence from straight-through..
Trying to compare them with (say) LGB larger radius points, or working out 'roughly' what sort of radius/diameter would match-up, is my problem.
But I am guessing you would not tend to have a curve straight off a point, prototypically?
