We have been fortunate to acquire a few of these now scarce tools which were used for dismantling parts of the Vicker's, particularly the muzzle attachment etc. It was carried in the section tool wallet. In near as new condition, however due to the condition and import costs from the old colonies (thankfully the UK didn't join in the Tarif war!) we have had to put the price up
Photo shows typical examples, units priced and sold singly i.e. price is for one (1) tool only)
