I could suggest Dave lewis who was working with Mike on the service side of things, he may still have some parts available although it's been some years since I was in contact with him.

Should you wish I will forward his number to you if you P/M me as it is probably a personal mobile, it may be a day or so until I respond as I have a lot of building work going on at home at the moment and am caring for my partner as she is recovering from a bleed on the brain.

I would not like to veture on spare part prices, it may be worth trying Best Fittings for an adaptor if no machinist is available.

I can also confirm from personal experience that the fill adaptor fitterd the MK1, MK2, MINI & R32 & R32 Ultra models unless anyting was changed accross the range as I have ownded all the listed variations.

From memory I don't think I have a spare origonal Magazine but will check.

Regards, Nigel.
