It sounds like you’re looking for vintage silk thread in size 00 or A, in gold 16, specifically for wrapping bamboo fly rods. Here’s some helpful information:

1. Understanding Silk Thread Sizes for Fly Rods:
– Size 00 (or A): This is a very fine silk thread traditionally used for delicate wraps on bamboo fly rods. It’s ideal for lightweight rods where a thin, smooth finish is desired.
– Gold 16: This refers to the color (gold) and the specific dye lot or shade (16). Vintage silk threads often had numbered color variations.

2. Where to Find Vintage Silk Thread:
– Specialty Fly Fishing Suppliers: Some companies still produce or stock vintage-style silk thread for rod building:
– Gudebrod (discontinued, but NOS—New Old Stock—can be found on eBay or forums).
– YLI Silk (still available in some colors, though exact vintage matches may be hard to find).
– Pearsall’s Gossamer Silk (a popular choice for classic rod builders, available in many shades).
– Online Marketplaces: Check eBay, Etsy, or vintage tackle forums (like the Classic Fly Rod Forum or Fiberglass Flyrodders) for old stock.
– Antique Tackle Shows/Sellers: Some dealers specialize in vintage rod-building materials.

3. Modern Alternatives:

– If you can’t find exact vintage thread, modern Belding Corticelli, YLI, or Kimono Silk (size A/00) can be good substitutes.
– Color Matching: If 16 gold is unavailable, you may need to blend or over-dye to achieve the right shade.

4. Tips for Use:
– Silk thread requires varnish or epoxy to seal and protect the wraps.
– For a traditional look, use amber shellac or spar varnish over the wraps.
