Photographic negatives, chronological series The original references consist of a six digit code, followed by a slash and then a numerical range, e.g. 280101/1-36. The first six digits are the date, in this case 28 January 2001, and then the numerical range is the number of the negatives held in that particular plastic folder. A few stray negatives were found in 2021/22 during the MBH Box project. A note attached to these suggests that they may have been loaned out at some point, and the note also indicates that they form part of TH/8475/5, although the original reference codes are missing. These negatives, together with an explanatory note, have been placed in the box containing L/THL/K/1/4/1-7 at Stack 22: 1C.
