How do I as (nowadays anyway, an outsider) access such historic
snapshots of the IP address range, before today's ISP acquired them.

Is this a 'service' that RIPE NCC offers (and hence my question in this
forum).

Sometimes the answer is "we aren't allowed to tell you - because of data
protection". But I suspect the dirt was acquired by a user outside the
EU, and hence arguably outside the protection of EU DP law.

If I were the admins in this case, I would have (weeks ago) demanded
"some new clean ones", seeing as how the process of cleaning the current
ones is proving less than adequate.

But unfortunately the customer organisation is part of a consortium, and
you'd need to get a lot of *other* members on side.

Being able to say who attracted the dirt, is my motivation for assisting
in an attempt to get a critical mass of consortium members to act.
