I do not see an attached photo.

Open the cabinet and take a photo of the back of the magnet too. That will make identification of the transducer easy.

That is a Tannoy "Silver", as they are referred to today. LSU/HF/12L is the official Tannoy name for the driver.

The cabinet is the Tannoy GRF.

More information about the driver here; https://www.hilberink.nl/tannoy/flyer/tannoydcflyer2.pdf and here; https://www.hilberink.nl/codehans/tannoy52.htm.

THE FIRST TANNOY DUAL CONCENTRICS

>** The terms Black, Silver and Red have been adopted in more recent times by owners, but they are
not original Tannoy titles and were never officially used by the manufacturer Tannoy LTD.
The only officially "coloured" Tannoy was the Gold, Tannoy LTD used 'Monitor Gold' as a trademark.
(Dermot Elworthy)"

THE MONITOR SILVER

When the 15" Monitor Silver was announced, the crossover network was separated from the chassis to
prevent interactions with the ferrous magnet parts. The 15" Monitor Silver was also used in the Corner
GRF loudspeaker system launched in 1955. The 15" Monitor Silver was accompanied in 1957 by a smaller
unit, the 12" Monitor Silver, which was the predecessor of the famous Tannoy Little Red Monitor
launched in 1979.

The Monitor Silver range of 2 units continued in development with improvements to power handling,
sensitivity and free air resonance through 2 more generations before significant changes took place.



I have a friend that has a single 12" Silver and is looking for another. If you would like to part with yours please contact me via PM and I will pass on your contact details.

Not a GRF cabinet.  My guess is a corner Canterbury.
