I have read that for companies like BSA and Triumph used production brazing method by pinning joints and furnace brazing. Does anyone know the type of brass and flux used by British bike builders like Rickman? I have had instances when joint repair is required on a restoration. Most recently I have a kick stand pivot on a BSA lightning to repair. It may not be necessary to use the same brazing components as they used but it would be interesting to know since their brazing produced good liking fillets.
