It looks like you’re searching for a vintage-style waist pack or tackle bag designed for fly fishing, possibly resembling the classic Plano tackle boxes with a belt or waist-mounted design. Here are some suggestions and options to consider:

1. Plano 3600 or 3500 Series Waist Pack
– Some anglers modify Plano StowAway tackle boxes (3600/3500 size) by attaching them to a fishing belt or waist pack system.
– Look for aftermarket waist straps or MOLLE-compatible belts to secure the box.
2. Vintage-Style Fly Fishing Waist Packs
– Brands like Fishpond, Orvis, or Filson offer retro-styled waist packs with multiple compartments for fly boxes, tippet, and tools.
– Example: Fishpond Thunderhead Submersible Waist Pack (waterproof, vintage aesthetic).
3. DIY Vintage Waist Tackle Bag
– Search for military surplus or vintage canvas bags that can be repurposed with Plano inserts.
– Leather or waxed canvas options give an old-school look.
4. eBay / Etsy for Vintage Fishing Gear
– Search for “vintage fly fishing waist pack” or “old-school tackle belt” to find unique, used items.
