Paul Seddon was the boss of ‘Parba’ in the 1960s until he got together with Alan Waterhouse and Tony Howard to form ‘Troll Equipment’ in 1970. These Big H’s were one of Parba’s products and have been threaded on this piece of rope along with a wee Troll wedge. We wonder if the person who threaded them knew that Parba and Troll had amalgamated! Not sure where we got them from, though they are a nice little addition to our ever growing collection of early rock gear.
