It sounds like you’re looking for vintage silk thread in size 00 or A, color Orange 6, specifically for wrapping bamboo fly rods. Here’s what you should know:

1. Understanding Silk Thread Sizes for Fly Rods
– Size 00 (or “A”): This is a very fine thread traditionally used for delicate wraps on bamboo rods.
– Orange 6: Likely refers to a specific shade of orange (possibly a classic “Gudebrod” or “Pearsall’s” color code).

2. Where to Find Vintage Silk Thread

Vintage Silk Thread for Bamboo Fly Rods Sizes 00 OR A - Orange #6

Since many classic silk thread brands (like Gudebrod, Pearsall’s, Belding Corticelli) are no longer in production, you may need to search:
– Online Auctions: eBay often has vintage silk thread spools.
– Specialty Fly Fishing Forums: Check forums like [The Classic Fly Rod Forum](http://classicflyrodforum.com) or [Bamboo Rodmaking](https://www.bamboorodmaking.com).
– Vintage Tackle Shops: Some shops specialize in old fly-tying materials.
– Rodmaking Suppliers: Some modern suppliers carry reproductions (e.g., YLI 50 Silk or Kimono Silk).

3. Modern Alternatives
If you can’t find exact vintage thread, consider:
– YLI Silk 50 (similar to size A) in a matching orange.
– Pearsall’s Gossamer Silk (still available in some colors).
– Kimono Silk Thread (used by some rod builders).

4. Color Matching
If “Orange 6” is critical, try:
– Comparing to old Gudebrod color charts (archived online).
– Asking rod restoration experts for closest matches.
