One of those sad cases where I haven't been able to find a name for a company and have been reduced to using its singles prefix as an identifier. 'DT' appears to have hailed from Northern Ireland: the 'Rathfriland' and 'Omagh' of Peter King's 'Rathfriland On The Hill' b/w 'Pretty Little Girl From Omagh' (DT-002; 1978) are in that country; while Rock band Chalkie, whose tracks 'Rock Me Angel' and 'Just Another Day' made up the two sides of DT-003 / DT-004, were from Bangor. That single, too, came out in 1978. Presumably there was a DT-001, and possibly some more DTs from 005 onwards. If anyone knows of them I'd be happy to hear details.
