Blaster for the win, as usual.
The Fullerton is a fascinating shoe - six-eyelet bal but on the 1 last, which I believe makes it unique. Strangely, it doesn't show up on the website when you filter the "all" list by the 1, which is often how I look for shoes (the 1 last being my favorite).
And, as kmdsimpson suggested, it could be the "one shoe to rule them all." Split-reverse or flat welt . . . shell, smooth or grain calf . . . any color . . . maybe even a Strand medallion. So many different looks possible here.
(I just noticed that this MTO version only has five eyelets. Blaster, how did you pull that off? It's not in your specs.)
I had the same question; forgot to ask. Perhaps Bl@ster has a small foot? Curious to hear the answer.
