Unicraft is a one-man model company from Ukraine. He has great model designs and the masters are usually top notch, but the resin products are typically very "rustic". Parts usually have huge gaps or other issues (poor resin, surface defects, etc.). They're buildable, but they require a lot of effort and patience as well as a well stocked parts bin. I think Tophe has done a great job with a few Unicraft kits.
Igor used to make plastic models - he would heat a sheet of plastic and push it into a mold... by hand. You would occasionally see a part with a fingerprint embedded in the plastic. All the parts had one side covered by a scorched, carbonized material (paper?)
