Looking for a Tau Tiger Shark part

This is a long shot, blind folded, and in the dark hanging upside down, but I'll throw it out there anyway. I am looking for a cockpit access hatch for the Tau Tiger Shark model kit I own. Lost it in a move somewhere. Forge World will not hook me up, really not sure if I got the part in the first place but it's been ages since the purchase date.

Thanks for reading.

Ebay or Dakkadakka are your best bet.
