Tannoy loudspeaker specs needed

Hi there all. Does anybody out there have any info for a set of Tannoy drivers I have just purchased. (two horns and two base drivers for $110.00 NZ)
These units look similar to the Oxford loudspeaker setup, but has an 8 inch driver instead and the horn has a bullet centre and metal facia on both are a gold colour.
The numbers on the horn are 7800 0085 1108g and the base driver has 1984 (the year I suspect)
Any info ie power, freq range of each and whether sealed or ported enclosures.
Many thanks from down here in New Zealand.
