So now the frame's significant other: the fork.
Same process as for the frame. The fork crown seems to be investment cast (not forged/welded) and the underside finish is rather coarse (but who's going to look down there?)
Please notice the white dropouts. It's a distinctive trait in all my restored frames (well, the white rear bridge too...)
Why? There's no particular reason. I painted this way my first frame and I've kept doing so. A mere eccentricity...
