Bronze brazed? If my memory is not flawed, they (Rickman frames) were welded using a 125,000 psi nickel-copper-silver rod. The flux was added into the flame which made the flame green. I think this is probably about the same stuff that a friend of mine uses to put carbide teeth on saw blades. He calls it "silver solder" which is probably nearer the truth than "bronze braze". Either Certainium Alloys and Research or Eutectic+Castolin can supply something similar.
