Mick, Morrison Kyle’s two volumes from 1856 showed top lines of music only, no arrangements or mention of TS Gleadhill. Vol ll has the Oswald/MSS tune. As you say the 1876 book has the new tune by Gleadhill and I’m waiting for an answer from Manchester Library which has an 1873 volume.i suspect it will also have Gleadhill’s version which would be the first printed copy unless TS Gleadhill printed some of his work before publishing his arrangements with Kyle, who died in 1879 according to info on the web. This would explain the 1880 edition being published by Joseph Ferrier. I noticed Archie Fisher on his Orfeo LP, 1970, claimed to have written this tune for Silver Tassie. Archie was a good friend and I think it might just have been a ‘clerical’ error.
