Canberra Jack Help

Hi all

Is there anyone out there who might be able to help, I am looking for the following AP for our Canberra 5 ton nose jack (AP119K-0124-16), we are also looking for a source of replacement seals for the same jack, as ours has given up the ghost and we will hopefully need the jack serviceable in the next few weeks as we start to reassemble xh131. Any help would be greatly appreciated.
