Hey everyone! And welcome to the forum Live4Kawstoomz! I’m excited to see some interest in Dustin’s S3 wardrobe!
The patch actually isn’t as straight forward as it seems. There are two sizes of the Walker Garn (51D) patch, one being 5”x4” and the other 4”x3”. I’ve found a 5”x4” 51D that does share more similarities than the 4”x3”, but it’s way too big. And still, neither are an exact match to his, and both sit too large on the vest. Then we have the Baudry Garn (51E) patch. The 51E is a hair smaller than the 4”x3” 51D (and a slightly different shape) and includes the small details missing on the 51D. It looks like they combined qualities from the two patches and made the patch we see Dustin wearing. Here’s a comparison to show the differences and similarities:
You can see that the continuous blue border, the version of the ship, the distance between the Earth and the three names on the bottom, and the distance between Bobko and the top of the flag, are all closer on the 51E. Although there are still details like the water on the Earth and the right portion of the flag on the 51E that aren’t an exact match. But essentially, if you took a 51E and replaced the bottom names with Walker and Garn, and replaced Challenger with Discovery, you would have a pretty good approximation. So that’s what I did here:
The problem is that the Discovery is a little too big for the 51E, and I think Dustin’s patch is still even a little smaller overall. But it is a pretty good match. I haven’t ironed this onto my vest yet because I’m hoping that someone might take a stab at replicating this exactly. (Anyone?

) In the meantime, here’s how it looks with the rest of my Dustin getup!
I managed to identify his shorts, shoes, walkie, and vest, and got the Levi’s hat and screen accurate print of the t shirt! I also have a good chunk of other wardrobe and props from S3, (lots of Dustin!) but didn’t want to hijack this thread too much!

Let me know if you want any info on anything!
I hope you have as much fun putting your wardrobe together as I have, and I wish you all the best!
