Vintage La Savinelli Giubileo d\'Oro 405 Unsmoked Pipe (Italy) For Sale

This is a Vintage La Savinelli Giubileo d\'Oro 405 Pipe, Made in Italy. 405? Yes it\'s a real Giubileo d\'Oro 405. Doing research, I come up with three things; its a stamping error, it was made for display purposes only not intended for sale, or is a line of pipes that was discontinued after a short time during the mid-century. This pipe is unsmoked and in great condition. The smooth brown bowl and shank look good. I do see a couple of small line marks on bowl, nothing really noticeable. The original stem with the three dots on top and metal airflow insert fits firmly into the shank. The bit/lip are in new condition. Airflow is awesome in this pipe. Pipe identifies correctly with Savinelli stamping with LA SAVINELLI over GIUBILEO D\'ORO on the right side of the shank and the Savinelli Shield next to a clear 405 over ITALY on the right side of the shank. Please see all pictures and let me know if you have any questions. Also, if you have any information on a 405 style, or its history, I would love to know.
