Help. Who made these figurine kits?

Several years ago I acquired a number of 25mm pewter (or lead) fantasy figurine diorama kits that had been opened and carefully placed in separate plastic drawers in a small parts cabinet.  There are paper cards with each one that give the name of the scene, a part number, and a B/W picture/sketch of the completed model.  They appear to all be by the same manufacturer but I have never been able to trace down what company made them.  Apparently they originally sold for $12-$14 each but I have no idea what they are worth or if they are rare.  Dates marked on the bases are from the early '90's and the detail is quite good.

Here's what I have:
#1023 Blood Tor, #1026 Immortal Combat, #1028 Knights of the Air, #1030 Dead Man's Chest, #1032 Mummy's Favorite, #1033 Magic Carpet Ride, #1034 Dragon Knight, #1035 Dueling Wizards, #1036 Sea Changes, #1037 The Sorcerer's Apprentice, #1038 Saved by the Bell

I'm about to start building them but I'd hate to do that if they are worth something as collectables. Can anybody help me out with a little background info?
