Driving through the village of Thropton the other day, I noticed similar 30mph markers, very much the same as those at Eglingham. I must have driven through there (at 30mph lol) hundreds of times without seeing them. At a guess I`d say these and the Eglingham markers date back to the the late sixties, early seventies. Is just a guess though!
This image (below) was taken on the day of my sojourn at Eglingam. It may well be an Alnwick Foundry signpost; can `t say for sure as there are no markings indicating who the manufacturer was/is. Still it`s an interesting post, cannot deny that. Quite unique, one of a kind!
It has been given a coat of paint. Say no more!
