Monday,21st September,2015,Autumn Equinox - it is now Autumn…golden-brown leaves…Golden Brown,a great song-record by The Stranglers

Guy Big J4T Gardner 8LXB 240-250 Tractive Units.
The Conclusion - well,I can always live in hope!

As promised in my very recent posts,here is the information that provides conclusive proof that Guy Motors,of Fallings Park,Wolverhampton,
a division of the BRITISH LEYLAND Truck & Bus Division,did indeed genuinely build and produced Guy Big J4T 4x2 Gardner 8LXB 240-250 Eight-
Cylinder In Line Straight Eight Diesel-Engined Tractive Units from 1973 to 1975.
29 Guy Big J4T 4x2 Tractive Units were built with a Gardner 8LXB diesel engine installed in each one of these lorries.
Guy announced in the Commercial Motor in 1973 that the Gardner 8LXB 240-250 Diesel Engine was to be made available in Guy Big J tractive units.
And 29 Gardner 8LXB - engined Guy Big J tractive units were built,and all had the optional 9Ft 6in wheelbase and all were fitted with the
Fuller RTO 9509 Gearbox.
Unfortunately,no known photographs of any angle and view exist of any genuine Guy factory-produced Guy Big J4T Gardner 8LXB-engined tractive
units. There is a 1973?,or 1974?,Commercial Vehicle Motor Show photograph of a white Guy Big J4T 4x2 Tractive Unit which could have a Gardner
8LXB engine in it,and I think this particular Guy lorry went to Smiths of Madiston - the operator with the largest fleet of Gardner 8LXB-engined
Guy Big J tractive units.
Photographs are not that important if you have written evidence,and we’ve now got written evidence that proves that Guy Motors actually
built 29 Guy Big J4T Gardner 8LXB -engined tractive units!!! EUREKA!!!
Please QV below and look at the photocopied evidence from
the archives of THE BRITISH COMMERCIAL VEHICLE MUSEUM! 
I just asked the right questions,and BCVM Archivist,Gordan Whittaker,did the fascinating research - well done Gordon and thank you very much! 
The historic details below were taken from Guy Motors production records that are now in the safe keeping of the Archive Division of The British Commercial Vehicle Museum.

Gordon Whittaker’s note to me:-

Guy Big J4T GARDNER 8LXB 240-250 Eight-Cylinder In Line Straight Eight Diesel-Engined 4x2 Tractive Units Production Details,Chassis Numbers,Engine Numbers,Dates,Operators,etc,from the Guy Motors archives in The British Commercial Vehicle Museum,Leyland,Lancashire:-

The blue-painted Wall of Liverpool restored and preserved Guy Big J4T 4x2 Gardner 8LXB 240-250 Diesel-Engined 4x2 Tractive Unit,PWK 914M,
registered on Tuesday,25th June,1974 is not a genuine Guy factory-built Gardner 8LXB-engined Big J. It has an 11Ft 4in(?) wheelbase,a Spicer
gearbox and was originally engined with either a ■■■■■■■■■■ Rolls-Royce,or Gardner 6LXB 180,or AEC diesel engine.It was originally a tractive
unit,but it was converted in to a heavy recovery vehicle - HRV later on. It was re-engined with a magnificent Gardner 8LXB 240-250 Diesel Engine,
it’s present engine.
The question is do any genuine Guy Motors factory built Guy Big J4T Gardner 8LXB 240-250 Engined 4x2 Tractive Units still exist?
Twenty-nine - 29 were built,they were rare when they were new…so they’ve got a low chance of survival - BUT I bet most if not all of those
29 Gardner 8LXB engines have survived!!!
Gardner diesel engines were,and still are,at a premium and they go on in to further service once
their original motor vehicle applications have been scrapped,either powering other motor vehicles,or boats.or generator sets,or whatever.
But fate may turn up one or two genuine Guy factory built Gardner 8LXB-engined Guy Big J4T tractive units yet
…
And now for another mystery…well it is to me! 
With respect,Bewick,how the hell do you pronounce your name?..I’ve often wondered 
Is it BE - WICK, or “Buick” as in the famous marque of American motorcar? Please solve this mystery.Thanks.
Guy Big J4T Gardner 8LXB 240-250 Tractive Units.
THIS CASE IS NOW CLOSED 
We can always live in hope… 
I love mysteries,so somebody please open up another motor vehicle mystery,please
