Recently, found these two, nearly identical, recipes in totally different spots -- one in a recipe booklet touting Comstock products; the other on a website for Sun Maid products.   My hunch is that the Sun-Maid folks “adapted” the older Comstock recipe, changing the glaze by cutting out the cream, using walnuts instead of pecans and, of course,  adding raisins.  Neither source gave credit for the original source of its version.    
The first version below, based upon Comstock's recipe, uses ¼ cup maple syrup in the cheesecake and ¾ cup in the glaze; while the Sun Maid, which appears second,  uses ¾ in the cheesecake and ¼ cup in the glaze.  The Comstock uses whipping cream in the glaze, the Sun Maid uses cornstarch as well as the raising and walnuts.

¼ cup sugar
¼ cup butter, melted

In large mixer bowl, beat cheese until fluffy.  Gradually beat in sweetened condensed milk until smooth.  Add pumpkin purée, eggs, ¼ cup maple syrup, cinnamon and nutmeg.  Mix well.  Pour into prepared pan.
Bake 1 hour and 15 minutes or until edge springs back when lightly touched (center will be slightly soft).  Cool.  Chill two to four hours.  Make glaze so that it can come to room temperature prior to serving atop cheesecake.
Prior to serving, drizzle with glaze.  Refrigerate leftovers.
