    far as I know it is vintage. The round emblems I believe are newer and have the upgrades from the older models. They round eblem usually brings more money on the used market.

    Basically, the difference is what emblem was put on the unit! Minor electrical changes were made over the life of the production and Service Bulletins were issued so that these changes could be made in the field. There are actually 4-different emblems starting with the "winged emblem" which was followed by the "round emblem" with international orange, then the "round emblem" with blue, and finally the "round emblem" for Rockwell / Collins. The main thing that the type of emblem does is to give a relative notion of just when the unit was produced. However, with the exception of the "Rockwell / Collins" emblem, the other units were manufactured for several years.

    Because of the relative age, some people place a higher value on the actual emblem on the unit. However, if the Service Bulletins have been installed, there is no actual performance difference among the very early to the very late units.
