Adrian,
Some close-up work of Clevedon on Googlemap and Bingmap and the old 8th you mention is indeed the uphill par-3 hole I recall. I can also spot the green of the old "Hookers Hell" 14th hole. I recall the old 13th was a very nice par-3 and the previous hole, the old par-5 12th (now the 2nd) being an absolute hell hole for a wee short hitting kid with that huge sleep slope up to the green.
BTW, for those who don't know where Clevedon is, it's on the coast just short of half way between Bristol and Burnham & Berrow GC. Not a links course though, cliff-top/upland in style.
The Castle Hole, now the 8th, is pretty spectatacular. I've tried to find a photo, not easy, these are the best I've found -
Photo from the now 8th tee - 350 yds or so, cambers right-to-left so easy to run out of fairway and go into the left side jungle.

In the top left corner of the arial photo of the the Castle, can just be made out the current 2nd green, on top of a high ridge. The green of the old/NLE 14th "Hookers Hell' can be seen to the right of the Castle. The tee to the 8th hole, the hole seen above, is to the right of the Castle.
The Shirehampton website isn't working very well at the moment so I'll have to wait before analysing the course in greater detail. I do recall a playing partner ball hit his 2nd shot over the cliff towards the Portway (!!) on the 1st hole and lots of par-3's and shortish par-4's. Pretty roller-coaster terrain in places as well with a few cross-over holes. I don't recall the old 3rd, sorry! I do recall though a short par-3 on the front-9 where you hit over a very deep gully (I think the hole you mention as the 6th), and on the back-9 the short cross-over par-3 11th and later on a par-3 with a very narrow raised green followed by a very sharp right-left dog-leg hole. I think these might have been the 15th (as you mention) and 16th.
I also enjoyed playing an upland course not far north east of Bath called Kingsdown. It played on two sides of a road with many stone walls. I particularly remember a dog-leg par-4 on the front-9 that that had a deeply sunken green (a bit like the green on the 11th at Minch' Old) and a really memorable short par-3 also on the front-9 where you hit over what seemed like a mass of craters and bomb-holes to a tiny wee green closely bordered by a stone wall. I guess Kingsdown must be close to Cumberwell Park, which I haven't visited but have heard lots of nice things about.
Happy days down in the West Country!:)
