Home Guard In N Ireland

I am interested in pipe bands in the Ulster Home Guard and know already that there were pipe bands in the 2nd Antrim Battalion (P/M James Hyndman) and the 4th Tyrone Battalion (P/M Thomas Howard). I don't know if these bands were on Battalion or Company level.
But apparently there were also pipe bands in Edenderry (P/M Jack Anderson) and Strabane (P/M John Ashenhurst). Edenderry and Strabane were not the location of HQ of any of the Battalions. Were these pipe bands on on Company level? And if so, which Company of which Battalion.
I would also be interested in a list of Companies (with location) of each Battalion. Does that exist?
Any help will be appreciated.
