Marching with the Beatles; Band of The Irish Guards

The record claims it will mot become obsolete as produced with the most demanding standards of engineering. Never been played and partislly sesled as tgat wrap has opened up partially on edges. For one it has to be played on monophonic or stereo phonographs, otherwise known as a recordrecord player! There is some talk anout what size stylus to use to play it. I read Microgroove was the patented name used by Columbia in 1948. Well this album is by Capitol records and not sure how old this record is to know if microgroove means 1 ml vs. the .7 ml stereo groove.
