Replica/Copy of a Conn 6M Alto Sax Neck in New Condition

This is an aftermarket Conn replica neck for a Conn 6M alto sax. Looks just like a 30's vintage Conn neck, with double socket receiver, underslung octave key, and microtuner mechanism (working). Everything looks right, and the neck is practically in “new” condition, with no major wear of note. Not sure who actually made the neck though; there's no markings on the neck anywhere. The inner neck tenon sleeve/receiver measures .876”.
