The Dyson looks like an early model DC07 from 2001, as I can only just make out the ID plate doesn't say made in Malaysia, and they were all made there after 2002.
The early DC07's made in the UK also had the round plugs, but also had the old style mark 1 cyclone systems which clogged up easily, so it would pay you to remove the top handle occasionally and check for clogs around the tops of the cyclones. Later models were de-rooted so the clogging was less of a problem.
Its a nice early example that's been well kept - but take care with it, as the early ones become very brittle with age!
