No...steering rake is 30 degrees.
Trail is 4", which I think is an American measurement, not sure how they do that in Europe, but might just be the same measurement in millimeters or centimeters.
I wouldn't worry about geometry as built, just go ride and enjoy it. If it turns out you just don't like the way the bike handles then sell it to another enthusiast. Changing head rake isn't easy as far as I know. I think you would need custom triple clamps or something. Or a weld job.
Custom building is good. I just wouldn't take this one and try and make it something it's not. But yeah, send some photos, I'm sure we'd all like to see what you're doing.
