Request

What hilo/two-tone siren models were used on 1966/67 AEC/Merryweather TL's during the 80's particularly 1986/87?

Response

Our Museum team have provided the following information:

In terms of London Fire Brigade, there were 17 AEC Merryweather Mercury 100 ft turntable ladders that were added to the fleet between 1962 and 1966. Most of these were disposed of before the time period in question (1986-7) but we know there were five on the fleet list in 1986. All were disposed of by 1988.
Unfortunately we do not have details of the two tone siren that may have been added to the turntable ladder. It might be of interest to the enquiries that the F108 Dennis appliance was the last appliance in our fleet to have a manually rung bell and the first to have a two tone siren, and this was introduced to the fleet in 1969.
The enquirer could reach out to the Fire Service Preservation Group, who preserve equipment and appliances and may be able to help further.
