Spinnaker Pole end for 50mm OD Tube

[BMP_Express]

Hi all, I'm looking for a spinnaker pole end fitting to suit a 50 mm outside diameter 46 mm inside diameter spinnaker pole as one of ours has broken. Ideally looking for one with an external trip, like the below. Does anyone have one they'd be willing to part with (or a whole old pole even ~ 3m long)? Happy to pay for postage or am around the Solent/Oxford/London areas at the moment.

Thanks in advance,

Bryn
