Hi Pal,
Welcome back to OFP and OFPEC. I am sorry that nobody has replied to you up until now.
I have kept many of my hard disks from PCs where I played the original OFP and do intend to go through them all at some stage to see what I can retrieve. I have 3 desktop PCs, the one I am using running latest Windows 10 Pro, an old one running XP and Linux and another one that will be running Win 7 Ultimate, when I set it up.
I will bear in mind what you are after and will post on here if I find those mods, but I have a lot of other stuff going on, so please do not expect anything anytime soon. I still have a very over-ambitious OFP mission that I last worked on at least ten years ago, that I am determined to finish sometime...
