Will have a look now in my 40k box now and see any marines I've got.
Not many as I had a genestealer cult army (shows my age)
and later nid swarm - I still remember the first time over 100 nids were in close combat on turn 2 - that was a lot of attack dice
Edit: Found some
Original Plastic's (RTB01)
And a set of the very first metals (LE2 & C100)
Now I just need some paint... and time
