MA 819 'Barnsly Chop' Gifts of War – Presentation Spitfire

Hi,
I’m writing a short article, for a local family history society about the presentation spitfire, MA 819 ‘Barnsley Chop’,bought with the donations of the people of Barnsley.

Details about the plane: when commissioned; flight history; where based; when decommissioned would be most useful. An image of the plane would be a bonus.

I’ve downloaded details from http://www.airhistory.org.uk, about the plane, but I cannot find what the following abbreviations stand for: ARF; FRU.

Any help would be appreciated.

I’m also interested in the same details for P 8658 ‘Borough of Morley spitfire.

I look forward to hearing from you.

Best wishes,

Jeff
