I bought some very high quality packaged S/S fixings in A4 from a small stand upstairs. (It was right against a wall) They included solid screw cups and screws & washers of all sizes. Packs were marked "Marinetech" and "EDLESTAHLE Rost frei"
Does anyone remember visiting a stand like this? They also had good stocks of S/S eylets, rigging and electrical bits.
