I use git(-svn) to do my ofbiz work(as many here probably know). Currently, the svn is hosted on apache.org servers. When it was imported, the history was started fresh. This was done back in July, 2006.
However, that wasn't good enough for me. I dug around and found references to the previous svn repo, and have stitched that together locally(using what git calls grafts). That repo was at svn.ofbiz.org. This gets me back to August, 2003. But I'm still not satisified. Atm, I have git cvsimport running against the cvs repo hosted at sf.net. This one will take a bit more work to integrate, as all the top-level dirs are separate modules, and I need to git merge them back into one repo. I haven't done this before, but hopefully that'll give me history going back to May, 2001(or so). Are there any prior repositories I could go looking in? ps: I've posted previously about how to stitch git-svn repos together. pps: What has been interested in this again is a client approached us that was running an ofbiz version that was made 3 months before the apache import. Having already stitched the older repo together made it simple(r) to find what they may have modified. ppps: Exporting this for others to use is complex. git clone won't fetch all the svn metadata. And you can't rsync the folder, as git-svn stores things in a native machine format; this breaks between at least linux 32bit and 64bit.
