I've just dug up the auction catalogue for the Killick collection (1992) and found that I had noted down the hammer prices of most of the engines. It was infact here, and not at the Absalom sale, where I last noticed a Scott SE for sale. It fetched £130 (plus premium), but I expect I found the £200 I paid at Enstone easier to part with than I would £130 ten years ago.
Other prices; several smaller Amanco open cranks ranging from £260 to £500 with a Six Mule Team at £1050, lamp starts mostly £2-3000 with a 4hp Blackstone at £5200, Petter M's £250-350. All in all none of the prices would look that out of place today exept perhaps the Lister D with wood chopper at £420 - I still remember the collective sharp intake of breath when that one went down!
