Incredible old classic from this famous tunnel project, and one of only a very few of such caliber in private hands! This is a beautiful, complete floater. It has great old labels and provenance, dating from the Tunnel dig in the late 1800s and early 1900s. It is sharply twinned. It has wonderful, rich lavender color in person! Repaired, very cleanly.
