Where did this company go or are they out of business?

MB Models, inc.
P.O. Box 8241, Festival Ceneter
Charleston, SC 29418

I would like to get there Iraq T-62 A conversion and I can not find them on the net.

Happy Modeling

Tom,
MB Models, as such, is no longer in business. Mike Bishop (I think is his name) no longer does armor items. I believe he is now in business as Blue Water (or Jacket) resin ship models and accessories.
I had several of his resin and white metal armor kits, but recently sold them off.
You may want to keep your eye on Ebay or check the vendors at model shows., for the Iraqi T62 conversion.
