Got registered today, Roosevelt, unlimited Garand, and vintage.  I'll likely use the K31 in vintage.  The coat is shaping up to a cross of a couple vintage coats, an old Champion's Choice that's going to have some really nice leather pads from an equally old but little used 10X jacket put on it.  Old buckles that get in the way will be going and I'll fasten up with velcro.  It's sun bleached and raggedy, but at this stage, I'm not buying anything new!
