Whale sink tap spares

Wighteyebrow

Sink tap on 2010 Autosleeper Lancashire (same as Nuevo) started leaking.

Friction washers each side of spout and an o ring need replacing.

Can anyone help with locating parts. Local plumbing shops have looked through spares boxes without success.

Autosleepers spares dept can only supply a new tap for £46 and have lots in stock. So last resort as plumb shop quoted £129.

Understand importers/suppliers are Munster Simms in Northern Island. Not tried to contact them yet as Autosleepers think they do not keep spares.

Search on net appears to only keep coming up with spouts for different model and no spares or washer kits.

Any guidnce would be much appreciated.
