I'd imagine you would do better putting the railway gate posts on dd if they are in good order. I reckon they would be demand for them.€160-170/tn is a great motivator for getting rid of stuff. Had 8-10 old railwayline gate piers that were pulled up when we widened gaps etc over the years. Great weight in them.
Have 10-15 gates to sell too. Galvanize ones probably ranging from 10-17ft at a guess. No rungs missing. At least 3 big concrete water troughs too if any one is interested.
Must do a stocktake and put the whole lot on Donedeal.
