§ Mr. Matherasked the Secretary of State for Northern Ireland how many unmarked detonators recovered from an unexploded bomb have been traced as having been manufactured for use (a) in Great Britain, (b) overseas, or (c) as part of old unmarked stock.
§ Mr. MasonIt would not be in the interests of security to give details of individual finds. There is, however, reason to believe that most of the unmarked British-made detonators recovered in Northern Ireland represent old stock.
