You might be able to find that vest on E-bay - I use a specific Ausable(out of business) vest for my bass/striper/walleye fishing and I found a replacement on there - eventually. Seems it wasn't a popular model - lots of other Ausables but not "mine" (short "wading" vest with bigger pockets).
For my trout vest I don't need the shorter length or the bigger pockets so I'm not real particular on brand or style. At most I carry a small Plano 3214 box(little bigger than a cigg pack) with assorted spinners/lures. a pack or two of hooks/splitshot, maybe a jar of powerbait and a box of worms. I probably only use half the pockets LOL.
Good luck on your search
