Can anyone tell me the correct barrel profile I have by these measurements?

What is the overall length of the barrel? Look at the specs on barrel manufactuers websites, it should get you a good approximation assuming your barrel is similar in length to the spec on their specific site.
 
I'm thinking it is one of these contours but I cannot tell where 'B' to measure because I can't see where there is a contour change. Measurement 'A' looks to be 1.20" and at the muzzle end closest point before the threading starts is .991".
