Surely at that date, and with a find well-documented enough for there to be a photograph of the scene, there wouldn't really be any possibility of its being described as being in Stevenston if it had actually been in Saltcoats. After all, Little Plum was able to identify the Pun Brae in Stevenston readily enough. It would certainly have been reported in the Herald at the time; I thought at first I'd even seen the report in the Herald Files " 100 years ago " , but that turns out to have been another find, in April 1908, by some people digging in their gardens at "Mount Pleasant, Townhead "; this one was 1895.
Both these discoveries are mentioned in an article I kept from the Herald around 1971 ( which came accompanied by the picture in question ) about Bronze Age burials found in Stevenston; it was written by the Alex Morrison mentioned above, who was a lecturer in archaeology at Glasgow and a Stevenston man himself. Apparently there were quite a few: as well as the two just mentioned, there were some finds at Ardeer which I think I've seen posted about elsewhere on 3T, and one at Auchenharvie in the 1960s.The cist from this last one is the one that's in the North Ayrshire Museum.
Not all the finds were preserved; only some urn fragments survived from the Townhead one , and it supposedly wasn't remembered for sure exactly where it was. But he was fairly definite about the Pun Brae one; he described the location as being " in the vicinity of present-day Schoolwell Street and Alexander Place " , which will no doubt mean something to the Stivonians (? ) among you.
Who, it seems, go back a good long way !
