They were a limited edition, only in the 100's (less than 1000). Grille is a pig on them, it is all plastic and the chrome peels off especially on the surround and after a stone hits it. It is really just an HZ grille with extensions on every second bar but missing the stainless surround (a bit like those dodgy Rare's HZ replica grilles). I had a few NOS upper and lower a while back, but they were never as popular as the HJ (vertical) and HX (horizontal) Statesman grilles, I think I ended up giving away the last ones I had. I just looked up while i'm typing and i've still got a fair few HX/Z and HJ ones hanging up in the shed (may even have some new ones somewhere) but the SL/E ones are gone. Biggest problem with the SL/E is as they are mid 1979 they all got the TH350 which was a pig of a box when it was first put into HZ and VB, if you ask anyone that was in service at the time they'll attest to all the warranty problems with them, GMH should have gone back to the Trimatic straight away rather than waiting until 1981.
