I think I may have that thread but I'll look at it in the daylight tomorrow to make sure. On the one spool I found, so far. The bulk of my stock is on the old blue/gray spool. It's 6/0 thread but as old as it is there isn't much wax to it these days. I used a lot of what I called golden yellow to tie some woolies the browns in my area would eat up. Literally.
I'll get back to ya.
