The topic title may say it all. I know that there is a far more updated version 5 of FIRS something available for download and that I can get the source code but the easier way is to just ask:
Can someone please give me a download link for the FIRS 0.7.5 newGRF?
I really like the way the engineering and farming supplies work there (it was kind of a cheat but a lot of fun!) - the next version (0.8 I think) changed this behaviour.
If there's no other way than to download the source code and try to compile it myself (either getting 0.7.5 to work or changing version 5) ... well, so be it - but at least I tried ^_^
