Question on the correctness/authenticity of these Rolex 703 Crowns

[jonthefisher]

I recently purchased what were sold as new in package Rolex 703 Crowns. They were in sealed package marked B24-703-0-G1 which I believe is the correct part number.

They have the long cornet and appear to be like the other 703 crown I have seen but they do not have any crimps and appear to be of monoblock construction.

Are these actually Rolex 703 crowns or was the package mislabeled?

I thought 704 crowns (monoblock) have a short cornet?

Unfortunately I can not get better pictures without opening the package which would make them non-returnable.
