The G minor PC appears to date from 1874 - i.e. from when d'Albert was 10! It's dedicated to his father.
Rex Stultorum reports:
I did some more digging and I think I found the g minor concerto. It's a piano reduction but it seems mostly complete:

Perhaps some enterprising pianist/composer (Leslie Howard mayhap?) would be interested in finishing it.
IMSLP describes this work as 'almost complete'.
..and what's the violin concerto listed?
There isn't one...

But there IS one listed in the Heinemann Foundation Collection - at least according to David Plylar, the author of the blog entry about the MS of the early PC in A.
Oh, that list. It would be helpful if people made clear what listing they were referring to - the context here was IMSLP.
The mention's here (under 'Orchestral'): https://blogs.loc.gov/music/2017/05/re-discovery-the-two-opus-2s-of-eugen-dalbert/ (https://blogs.loc.gov/music/2017/05/re-discovery-the-two-opus-2s-of-eugen-dalbert/)
Friends may find this video on d'Albert interesting - I certainly did!
