It sounds like you’re looking for vintage silk thread in size 00 or A, color Blue 7, 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 and intricate finishing work.
– Blue 7: A classic, deep blue shade often used in traditional rod building.

2. Where to Find Vintage Silk Thread
Since vintage silk thread is no longer widely produced, you may need to search:
– Specialty Rod-Building Suppliers:
– Gudebrod (discontinued, but some old stock exists)
– YLI Silk Thread (still available in some colors, though not always exact vintage matches)

Vintage Silk Thread for Bamboo Fly Rods Sizes 00 OR A - Blue #7

– Pearsall’s Gossamer Silk (used in fly tying, sometimes repurposed for rod wraps)
– Online Marketplaces:
– eBay (search for “vintage silk fly rod thread size 00”)
– Etsy (some sellers offer NOS—New Old Stock—threads)
– Classic Fly Rod Forum (forum members often trade/sell vintage supplies)
– Antique Tackle Shops: Some specialize in bamboo rod restoration and may have old spools.

3. Modern Alternatives
If you can’t find true vintage thread, consider:

– Belding Corticelli Silk (sometimes available in vintage colors)
– Kimono Silk Thread (used in restoration work)

4. Tips for Authentic Restoration
– Test the thread for strength—old silk can degrade.
– Use color-preserving varnish (like Al’s Color Rite) to maintain the blue hue.
– If exact color matching is critical, check Pearsall’s 7 Blue (a close alternative).
