Some objects from this season of work (along with Harageh, Lahun, Gurob and Sedment) were distributed after the Second World War in 1948 and 1949 by Hilda Petrie having been stored at University College London. In these cases it is not always clear which tomb the material is from, although the objects were (according to Hilda Petrie) distinguished by site with the use of letters: H, L, G and S, corresponding to the different sites.
