NO! NO! 
The above photographs show Guy Big J4T Tractive Unit-Articulated Lorries operated by Smith of Maddiston with the original front end sheet
metal styling,and these date from 1964 to around 1971.
All top weight Guy Big J tractive units for the 1971 model year et seq (introduced in 1970) had the new full length square-style, vertical oblong, two piece,fine mesh,radiator grille,which of course included all of the production Guy Big J4T Gardner 8LXB-Engined Tractive Units,including the one of 29 actually built,in the Peter Davies photograph below:-

Don’t take any notice of the misguided and wrong cynics: I have authentic objective proof of the 29 Guy Big J4T Gardner 8LXB Tractive Units that were actually built by Guy Motors Limited,Wolverhampton,WV10 9QF,from 1973 to 1975. 
The Guy Big J4T Gardner 8LXB Tractive Unit Mystery is solved. Really.
So let’s move on to another mystery now.
