Anyone recognise these mints

1) variegated mint - I think that the leaves are too narrow for ginger
mint - being grown on an allotment

When I used to grow one like that, I knew it as pineapple mint. That
doesn't mean to say it was right!

The one I bought as ginger mint had leaves the texture of apple mint
(though a lot smaller) and white rather than gold variegation.

You might have swapped those two in your recollection. According to the
RHS Encylopedia of Herbs pineapple mint is Mentha suaveolens
'Variegata', which is a white variegated (margined) form of applemint.
Gingermint is Mentha x gracilis 'Variegata', which is a yellow
variegated (centrally marked) form of redmint.

I'm not sure whether the photographed plant falls within the bounds of
variation of gingermint (which I've seen elsewhere), or whether it's a
parallel cultivar of a different mint species or hybrid. But gingermint
(usually) has linear yellow markings along the midrib and secondary
veins, and this as somewhat irregular markings.
