Very early Conklin Crescent 4 with a slip on cap. BHR, cap BCHR. 12.5cm closed, 16.8 posted. Clear imprint on the body and a number the end of the barrel. Very nice and very flexible, soft nib. The nib has a minimal bent/crack next to the breathing hole, which is visible under a magnifying glass and doesn’t go through to the bottom side of the nib, and doesn’t affect writing
