seeing as how the 3D helmets seem to have taken off, I'm going to be putting together the GPL Hat shop on the compendium. I'll be putting all my creations (FA Prem, NFL, Drivers, Nuneaton Boro(!)) on there as well as links (and only links!) to other peoples pages where their creations reside.
If there is anyone out there who wants me to host a copy of their file (in case they've just posted a file and they don't have a website) just let me know and I'll add it in, but I would not presume to do so until I'd asked the author.
To kick it off, I've done a Stewart and a Spence for the BRM. Check them here
