Anyone have 270 cal expander and turner mandrels for Sinclair neck turner?

I need to turn some .270 cal necks and have just realised I don't have .270 mandrels for my Sinclair turning tools.

I can get some from Sinclair's in the US but may take a while with the current dramas with NZ Customs.

Anyone happy to lend me the mandrels?

If you have no luck you could probably get them quicker & easier from BRT Shooters Supplies in Australia??
