I wonder about the "Big 6" designation. The front of this wonderful appliance looks identical to a "Light 6" of 1937 bar the radiator. Note too that "light 6" radiators and front end in the years following had a more rounded shape so the 1941 date is also intriging. Compare these photos with the shot of the York "Big 6" posted the same day and this appears to be much lighter in construction. Notwithstanding these queries it's an absolutly wonderful appliance.

Hi John,
No its definatly a 'Big Six' it just has the later bonnet styling, the radiator is original as well - certainly from before its restoration as I have a photocopied picture from its previous owner with the rad in place when it was being recovered from Shannon in Co. Clare, the York Big Six belongs to me and is 1934 vintage, see Dr B A Hutchinsons West Ham one as well it has the earlier bonnet and radiator, Scunthorpe Fire Brigade had a 1940 Big Six with the same bonnet as this but earlier radiator style, BFU 427. The more I think about it though the registration is /was GLW 668 and not 168 as I posted earlier - one train of thought re the radiator is, it was wartime and such niceties as the correct rad were not vital to the machine so, if a standard radiatior was not available but a non standard one was it would be fitted to get the appliance out - considering it was Hornchurch's machine, - just outside the east end of London this would have been desperatly needed.

This need for appliances and savings is proven with my Aberdeen Leyland Cub FK9a the only one built, after it was finished the authorities decreed that to save on vital materials there was no need for two sets of deliveies etc, as in a side/ midships mounted pump and only rear mounted appliances would be built hence the FK8a was the standard model ! My FK9a also has a brass radiator/ deliveries and windscreen all fitted as part of the main build but then chrome hinges/ handles etc and no 'fancy embellishments' such as deflectors over the doors etc.

Thank you Rick. Queries answered

Added by John Walker on 03 September 2008.
Rick - thanks, too.
I had also been puzzling over how a Rear-Mount Pump would save brass, over a Midships Pump - especially when the Rear-Mount would need a long drive-shaft and bearings, etc.

But, as you say, it is in the plumbing.

Hello All...
I have a photo of this machine when it was in brigade workshops at Lexden, Colchester awaiting disposal, not sure when taken but probably mid 50s.. Will put the picture on here soon.

I have this machine as chassis no 3115A with the reg no GLW 669 (not 168 ??) delivered to Hornchurch in 1941

Ok Barrie I'll go with that - perhaps a combination of 'lost in the mists of time' and perhaps one (or two) to many Guinnesses !!!!

Barrie,
Our records in Clare FRS show that this was GLW 668, chassis no 3115A, re-registered in Clare to 2406 IE. I dont have any record of it serving in Shannon (Although Dennis Light Four JHK 327 did). Our records show that GLW668 served in Kilrush Co.Clare.

GLW Reg would suggest 1942 GLR, GLT were early 1942

GLW668 Dublin museum catalogue entry reads

This Dennis was one of 84 mechanically similar vehicles built during the years 1935-1943 with various types of bodywork and known as Light Sixes or Big Aces. Ordered by Hornchurch Fire Brigade in the U.K., it was not delivered until 1942 when, registered GLW 668, it went direct to the National Fire Service, which was responsible for fire fighting throughout Britain during World War Two. When control of the fire services returned to local authority control in April 1948, the Dennis passed to one of the reconstituted brigades.
GLW 668 was one of several pre-owned appliances bought by Clare County Fire Service during the 1960s to provide improved cover for expanding towns and industrialisation. Re-registered 2406 IE in 1975, it served just until 1977 and was subsequently purchased by Sean Keoghan of Kilbeggan, who restored it, rallied it for several years and donated it to the museum in 2005.
This vehicle is currently on display in the Museum.

GLW reg is Greater London so NFS. My own light 4 (1943) was ordered chrome finish but on the order it’s scored out and noted as war finish. Pump parts left unpainted. Also have a Bristol hex drive socket set. Unpainted and marked as war finish too.
