What guard do I need?

[Stanley]

I have a Manton and Smith chrome guard like image 1. I really like that guard. I saw a similar bike with that guard.
I was also thinking an orginal paint Navy Blue with Cream pinstripes or Navy Blue with Red pinstripes like image 2.
My bike is similar to image 3 but without a guard.

Well, the yellow bike is a Shelby. The only other bike I've seen that chrome guard on is late prewar Monarks.

I’m pretty sure I’ve seen the chrome one on a few airflows
