The WordPress Custom Post Type Archive Widget Plugin displays a monthly or yearly archive of posts for one specific post-type. It is very similar to the WordPress Archive except that it just displays one specific custom post-type's posts, not all categories. It can be configured to either show a listing or a pulldown by month or year with or without post counts.
