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?

A quick Google search found this page. No prices though and all the items are listed as currently not available.

Thanks much, David. I’ve tried Google searching these 20 ways to Sunday and never turned up anything I could use. You’re GOOD. This is just what I was looking for.
