This really looks NOS except for the drive gear. I think some of the Mallory distributors came minus the gear and you had to use your original one. Points are new , bright plating on the breaker plate. Cap looks new as does the rotor. There is no wear anywhere on it. I am reluctant to call it NOS but is sure looks like it could be. I ran it on my Sun machine and it checked out great 24 degrees advance in at 3200. Missing the tag for some reason but the model number 550 is stamped in the housing 350 bucks plus 25 for lower 48 shipping https://www.youtube.com/shorts/9TeXd6-L1RE
