Ernie - Here's the information you need. Of course you can furnish whatever dimension that you need.
"I have discovered a new source for Anchor Bay Display Cases. The cases come with a light oak wood display base and have an acrylic plastic display case. The company is a large manufacturer of display cases for sports, doll, NASCAR, etc. collectibles. I talked to the boss about modifying a 1/18 scale NASCAR Display Case(Model D00-0018W) from their website to the inside dimensions of 12 7/16" W x 5 1/8" D x 5 1/2" H for the MACKINAW and he indicated that this would not be a problem and there would not be an additional charge over their normal catalog price of $28.53. The cost for each modified case will be $28.53 + $6.50 UPS shipping for a total of $35.03 per case. For this price you can have a prefinished light oak wooden base or they will leave the base unfinished and you can darken the oak base as you see fit. You also have a choice of a mirrored or unmirrored back panel. It will take them a week to modify the case to the above dimensions and ship it to me. I saw one of their NASCAR Display Cases in Daytona and was very impressed with the quality. Needless to say, I ordered 2 of these modified Mackinaw cases.
In talking to Jeff Sampson at 1-888-742-5567, he also indicated that they would consider modifying any of their other cases for other Anchor Bay ships that did not come with a case. He said that he would welcome other inquiries about his products. The name of the company is Clearwater Displays located in Binghamton, NY. Their website is www.clearwaterdisplays.com
and their phone number is 1-888-742-5567. They take credit cards and will accept your order from their website on standard available cases or over the phone for special modified cases."
